Arsenal travel to Wales to face up against bottom-of-the-table Swansea City on Tuesday evening, as the Gunners look to earn their third consecutive win in a row, a feat they have rarely managed this season. After securing a place in the League Cup final after defeating Chelsea in the Semi Final last Wednesday, the atmosphere around North London has improved. That, sadly, does not address the issue of poor league form, which is something that the manager will be hoping to address with a reignited side and perhaps the appearance of a new addition to the squad.Although Swansea have had a fairly torrid season thus far, they have just had their best league result of the season - a shock one-nil home win over a Liverpool side that had defeated Pep Guardiola's seemingly unbeatable Manchester City side just a few days previously. It was Alfie Mawson that found the net on the day against the Reds to give his new manager Carlos Carvahal an impressive win to boost morale around the Liberty Stadium.Only a couple of weeks previously, Liverpool registered a 5-0 win against the Swans at Anfield. In this short space of time, the Welsh side’s fortunes have seen improvements - they registered wins against Watford in the league and Wolves in the cup, as well as a respectable draw against Newcastle a fortnight ago. This upturn coincides with Carvalhal's arrival, and he'll be looking to continue his side’s good form in an effort to avoid relegation to the Championship.The game is likely to be the debut of new signing Henrikh Mkhitaryan who joined the club last week from Manchester United as part of a swap deal with Alexis Sanchez going the other way. Arsene Wenger was coy as to whether he would play the Armenian in his pre-match press conference, but it is hard to envision any reason why he would not feature.Debuts can go either way - Ross Barkley had an underwhelming beginning to his Chelsea career in the cup loss in midweek - although, it was his first game of the season - while Alexis Sanchez had a promising start to his time in Manchester, although in his case, he was facing a lower-league side.The former Borussia Dortmund man will be able to slot in either on the wing or down the middle of the midfield, and will act as an attacking threat. He will likely be accompanied by Mesut Ozil and Alexandre Lacazette in the attacking 4-3-3 formation that has been seen of late, with the two Arsenal stalwarts hoping to maintain the sterling form they showcased against Crystal Palace in the 4-1 win in the previous league game.Arsenal is likely to have some boosts when it comes to injuries for this match, especially in attacking positions. Danny Welbeck is expected to be fit, after being deemed just a fraction to unfit to feature against Chelsea in the League Cup, and joining him with a return to fitness is Olivier Giroud, who has been out since early December.The French striker has recovered from a hamstring strain and may play a part in the game. It is a timely return for these forward players, giving Wenger the option for more depth, with the enticing prospect of further additions to his squad before the January transfer window closes on Wednesday. The home side has some players out, but are generally in good shape. Swansea will assess Renato Sanches' fitness before Tuesday after the midfielder picked up a hamstring injury in the 1-1 FA Cup draw with Notts County, manager Carlos Carvalhal said.The Portugal international was taken off after 32 minutes of the fourth round clash on Saturday after he pulled up injured in a Swansea counter-attack. The promising Euro 2016 winner Sanches, who hasn't had the best time in England following his loan move from Bayern Munich, suffered the same injury in the goalless third-round draw with Wolves.No doubt about it, Swansea's biggest issue this season has been finding the net - only managing to do so a meagre 15 times this season - an average of 0.63 per game. With this being the case, it's not difficult to figure out why they occupy the foot of the table. Somewhat impressively, however, is that despite the lack of goals scored, they are only 3 points - and likely some goal difference - Brighton and comparative safety in 16th place, as is the tightness in the lower half of the league. With such a small margin between them and potential safety, you can be sure that Swansea will be hoping to get something out of this game, especially on home turf. While Arsenal will be significant favourites, it's difficult to rule-out the potential of the Swan's scalping another giant - all you have to do is look back to two weeks ago and Bournemouth's win against the Gunners to see what Carvalhal's side can aspire to do.Hopefully for Arsenal, the change in atmosphere surrounding the club will hold them in good stead and they'll be able to return from Wales with all of the points in check.In the match build-up, goalkeeper Petr Cech admitted that Arsenal's league form simply wasn't good enough at the moment to warrant a return to Champions League football. In a frank interview, the veteran goalkeeper admitted "Regardless of that (the competitiveness of the league), this season we have had so many games where we were not up to the standard we needed to be and this is something we need to address for the rest of the season. We should have far more points than we have at this moment."Hopefully the keeper, who sat out the League Cup tie with Chelsea, and his side will be able to begin making amends for some of the points lost in the first half of the season, especially considering rivals for the top 4 Tottenham and Liverpool dropped points in their last league outings. It all depends on what Arsenal turns up. If it's the one that turned up against Bournemouth at the Vitality Stadium, anything could happen. If it's the one that dismantled Crystal Palace Swansea will have their work cut out for them.Arsenal travel to the Liberty Stadium to face Swansea in the Premier League on Tuesday the 30th of January, with kick-off scheduled for 7.45pm.
