It is official - Pierre-Emerick Aubameyang is an Arsenal player! The Gabonese forward has been linked with a move to the Premier League for years, and now that move has finally materialized as he makes the move to North London.

After a fortnight of negotiations, a deal has been agreed between Borussia Dortmund and Arsenal for a club record fee of €63 Million (£55.5m). Even though it was technically a deadline day transfer, this deal appears to have been wrapped up in plenty of time, with the player flying to London Colney yesterday and a clip of Wenger speaking about the transfer being leaked from an official channel in the early hours of the morning.

English supporters will be familiar with Aubameyang from his Champions League displays and know of his undeniable attacking threat and incredible pace, but what else does the 28 Year-Old former African player of the year bring to the table?

One of the most enticing aspects of the Aubameyang transfer is the prospect of him linking up with former teammate and fellow new Arsenal player, Henrikh Mkhitaryan. The two players made up one the most threatening partnerships in the Bundesliga when they played together at Dortmund, with Aubameyang notching an amazing 141 goals in 212 games with Dortmund, with 80 of these coming while Mkhitaryan was at the club.

While making such a big signing is great, it does give a headache to management. Aubameyang's preferred and best position is that of a number 9... which happens to be the same as the previous record signing, Alexandre Lacazette, who himself has only been at the club a few short months. What does this mean? Can the two play together?

It seems doubtful. Lacazette and Aubameyang share many similarities - they're both poachers with great running speed. The two side by side won’t offer much in terms of a "target man", and certainly won't offer much defensively - not necessarily an issue with them being strikers, but when they are played with Mesut Ozil and Mkhitaryan behind them, it's a very attacking line-up, leaving things a little bare in the middle.

The most likely formations would appear to be a 3-4-3 with both Aubameyang and Lacazette, flanked by Mkhitaryan with Ozil in an attacking midfield role; or the same formation with the omission of Lacazette. Wenger may also opt for more cover at the back and the inclusion of both of his record signings, meaning he could go with a 4-3-1-2, with Ozil playing in the hole. This would, however, play Mkhitaryan out of his preferred attacking position.

In the middle of the field, there's also the issue of wanting to play both Aaron Ramsey and jack Wilshire if they're fit, and how the team will adjust to including all of these players. Perhaps it's not the worst headache to have, but it's likely it will take time to work out.

Perhaps it's surprising that Aubameyang wasn't an Arsenal player earlier in his career - in 2013, when Dortmund signed him from St. Etienne, he was perhaps the second most promising striker in Ligue 1. The most threatening striker from the league that season became an Arsenal player - Olivier Giroud.

In many ways, Aubameyang represented a player that more fitted the Arsene Wenger mould in that his pace outranked his target man status in terms of attacking attributes.

One thing that seems certain with the arrival of Aubameyang is that Giroud will be departing the club on loan to improve his chances of earning a place in the French World Cup Squad. Chelsea are believed to be the most likely to acquire his signature, with Michy Batshuayi joining Dortmund as a replacement for Aubameyang, completing a handy transfer triangle.

An impressive stat that has emerged following the Gabonese international's move is that since the start of the 2015/16 season, Aubameyang has scored a century of goals for Dortmund - 45 more than any Arsenal player has managed in that time.

It worth pointing out that Aubameyang, while being a technically excellent footballer, brought some baggage with him at Dortmund. By the end of his time at the Westfalenstadion, it was reported that the forward had become a "toxic" figure in the dressing room. Earlier in the season he had been suspended from matches for arriving late to training, and the previous season for breaking curfew and partying in Milan. It's also been reported that he (ironically) missed a team meeting on togetherness at the beginning of the season.

In the past weekend's match against Freiburg, despite playing 90 minutes, the want-away forward was booed with the famously passionate fans hoisting a banner reading "No One is Bigger Than Our Club". The writing was on the wall for Aubameyang at Dortmund for a while.

Even with this bad blood, Dortmund’s sporting director, Michael Zorc, said on the club’s website upon the news of his transfer: “Apart from the unpleasant episodes in the past few weeks we would like to remember that Pierre-Emerick Aubameyang at BVB was a real success story.", before wishing him well at Arsenal. Hopefully these incidents and reports don't ring through during his time with the Gunners and he can give a good account of himself at the Emirates.

Sadly, because of Borussia Dortmund's involvement in the Europa League following a 3rd place finish in their Champions’ league group, Aubameyang will be ineligible to be part of Wenger's 25-man squad for European knock-out matches. Incidentally, Mkhitaryan WILL be available for selection, so it's not all bad.

In the leaked clip following the Swansea match, Wenger acknowledged that Aubameyang had a big part to play in fixing Arsenal's attacking woes: “We need people who can give us more offensive power. At the moment, we aren’t enough going forward and I am convinced he will give us that.", the manager said.

“He has a big challenge in front of him. He wants to do well in the Premier League. It is absolutely good news for us. His pace, his finishing. The quality of his runs. His huge physical capacity, that will be important in the Premier League.” He added, showing that at least the manager isn't naive to the issues that face the team, and hopefully Aubameyang can offer a resolution to some of the side's problems.

If the result against Swansea last night showed anything, it's that there was need for refreshment in the squad. There isn't a team in the world who wouldn't be satisfied with signing Mkhitaryan, Aubameyang and holding onto Mesut Ozil in a January window, so even though things have been better, taking the window on its own merits, it appears to have been a success.
