Despite struggling throughout the biggest part of the season, Arsenal finished the 2016/17 campaign on a high, reclaiming the FA Cup trophy as they beat Premier League Champions Chelsea.

Arsene Wenger has just signed a two-year contract extension, therefore ending months of speculation about his future at the club, so that leaves only the situation of Alexis Sanchez, Mesut Ozil, and Alex Oxlade-Chamberlain the only major issues and something to be resolved during the summer. While much of our transfer activity depends on whether these players will decide to sign new contracts and stay at Arsenal, we analyze the key areas Arsenal should strengthen its squad this summer transfer window!

Striker

Undoubtedly, this is the most important and key area Arsenal should look to add. Having failed to justify the minimum fans expectations for last season, Arsene Wenger is under huge pressure to sign a prolific striker who is capable of scoring 20 + goals a season. Arsenal scored 77 goals during the 2016/17 Premier League campaign which is the fewest of all top five teams in the league and are in great need of adding someone who can play a huge part in improving last season's record.

Alexander Lacazette is probably the hottest name linked to Arsenal at this moment, with Olympique Lyonnais president Jean-Michael Aulas adding extra fuel to the speculations after admitting he might be open to selling his best player for the right price. There were reports that Aulas was in London this weekend to discuss a possible transfer, with a reported fee of around £50m. However, that could be lowered if reports are true that Lyon wants Olivier Giroud as a part of the deal. Lacazette scored 37 goals in 45 appearances for Lyon last season and with such an imposing record, he could be the perfect fit for Arsenal.

The French international is quick and effective type of forward, with a spur of nastiness in the way he moves his body. He started his career at Lyon and has recorded over 250 appearances for the Ligue 1 outfit. With 26 years of age, Lacazette still has his best years in front of him.

Kylian Mbappe from Monaco is another option for Arsene Wenger but the problem with him is that whole world seems to be chasing after his signature while an amount of £100 m is being mentioned in the press. I am not sure Arsenal can afford his services. The young Monaco winger impressed last season when he scored 24 goals and picked up 14 assists leading Monaco to the Ligue 1 title and reaching the semi-finals of the UEFA Champions League. With only 18 years of age, he is arguably the best young player in the world, with a huge potential and a big future ahead. Arsene Wenger has already flirted with the player admitting he is a big fan of Mbappe , while he recalled the time when Arsenal tried to sign him two years ago and the boss might feel he has a good chance of luring him out of Monaco as both share a mutual respect and solid relationship.

Right wing

Having switched to an old-fashioned 3-5-2 formation in the last ten games of the season, Arsene Wenger might decide to stick with his new formation, especially after seeing his team winning nine of his last ten games after changing their game plan. Alex Oxlade-Chamberlain and Hector Bellerin were assigned the right wing-back role and both of them impressed when given a chance. However, with reports suggesting Barcelona might make an offer for Bellerin and with Chamberlain yet to sign a new contract, Arsenal might need to splash the cash.

Ryad Mahrez is a possible solution and the Leicester City winger added fuel to the speculations by going publicly to announce his will to leave the club this summer. The Algerian international had a difficult season scoring just six goals, compared to seventeen when Leicester won the 2015/16 Premier League and it's logical he might be seeing his future at another club. However, if Arsene Wenger decides to play 3-5-2 the wing-back role requires big defensive tasks and responsibilities and I am not at all convinced by his abilities to defend. His price should be around £40 m.

James Rodriguez is one of the possibilities and could thoroughly fit the right wing position but Arsenal has not expressed such an interest in the player, with current reports claiming he is close to joining PSG. However, like Mahrez, James is a technically gifted attacking player, but you have to question if he can properly do his defensive duties.

Goalkeeper

With both David Ospina and Wojciech Szczęsny expected to leave the club this summer, Arsenal must find a quality replacement to avoid insufficiency of options when the season starts. That leaves only Petr Cech and Emiliano Martinez at the goalkeeper position. Martinez made just 13 appearances since joining Arsenal in 2012 and you have to question if he is ready to cope with such responsibilities. If Wenger decide to assign him as our No. 2 it will be a big gamble.

Jack Butland the Stoke shot-stopper is one of the hottest candidates and having just turned 24, could provide a long-term solution and a good backup for Petr Cech. However, his good form has provided an interest all across the country so Arsenal might face a competition in order to secure his services.

Bernd Leno another young goalkeeper with an enormous quality and an already rich experience. He is the potential successor of Manuel Neuer at the German national squad and having spent six years at Bayer Leverkusen, therefore making appearances in the Champions League, Europa League, and Bundesliga, he could be the ideal solution to Arsenal problems.

Right back

With reports claiming Mathieu Debuchy and Carl Jenkinson are almost certain to leave the club this summer, that leave us with only Hector Bellerin (we assume he won't leave for Barcelona) as the only option at Right back. We spoke previously about the options at the right wing-back position, but that is in case Arsene Wenger decide to stick to his formation. However, with Europa League campaign on the already busy schedule, the boss have to buy a proper right back.

Djibril Sidibe the Monaco right back whom Arsenal was linked with when he was playing for Lille two years ago, might be the right guy. He played a big part in helping Monaco winning the Ligue 1 and he could be available for £30m.

Cédric Soares having just sacked their manager Claude Puel, Southampton might face difficulties keeping their best players for the next season. With Virgil van Dijk and Ryan Bertrand already on the exit door, Cédric might be ready to follow them in search for a better future. The 2016 European Champion might be available for a little less than £20million.

Central midfield

Ok, this might raise a few eyebrows but if we closely analyze the situation at the center of the park, we would see that things are far from perfect in that area. Arsenal were long years famous for providing one of the best midfielders in Europe, with Patrick Vieira, Cesc Fabregas, Denis Bergkamp all playing their part in this conclusion. Last year, Granit Xhaka was our most consistent player at midfield, while Aaron Ramsey, Francis Coquelin, and Mohamed Elneny saw their time on the pitch fairly limited. Santi Cazorla picked up an injury which required surgery last December and Jack Wilshere was loaned to Bournemouth at the start of last season. If Jack Wilshere leave the club as many reports suggest and assuming Santi won't be back until October or November, It leave us with only four midfielders available. If Arsenal are to improve from last year, a creative box to box midfielder is needed.

Mateo Kovacic the Croat saw his time on the pitch at Real Madrid very restricted since joining the club from Inter and Arsenal might be his next destination in pursue for a regular football.

Aleksandr Golovin with only 21 years of age, if Arsene Wenger opts to sign the CSKA Moscow central midfielder, it is questionable if he'll be able to make a difference at our midfield. I suppose if this deal is about to happen, it will be just because he is viewed as a talent for the future, not someone who could make an instant mark on the squad.
