After scraping through the FA Cup 4th round away to Preston last week, Arsene Wenger is undoubtably going to make changes to his starting eleven against Swansea on Saturday.

Although the Swans are struggling in the Premier League this season, it could well be a tough test for the visitors to conquer as the Welsh side are under new management. Paul Clement has taken over at the Liberty Stadium, managing just one game so far, and winning 2-1 away at Crystal Palace.

On paper, this would be an easy win for the Gunners, but as we all know too well by now, the Premier League is full of surprises, and there is no doubt Arsenal will have to field their strongest possible eleven to succeed in getting all three points.

Luckily for Arsenal, key players have travelled to Wales for Saturday’s game, giving the team, and fans a boost for the upcoming game.

Here are the THREE Arsenal players who must start this weekend..

Alexis Sanchez

One of Arsenal’s best players who will be key to their potential success on Saturday. The Chilean was rested during the FA Cup fixture, so should be fresh and raring to go against Paul Clements side this weekend.

The Arsenal winger’s work rate and determination is unquestionably the greatest in the North London side, and with a weeks rest, it could be frightening how quick he could come out of the blocks.

Mesut Ozil

The German playmaker is a magician with the ball at his feet in the attacking third. Not only will the fans be happy to see him return from his illness, his teammates will also be lifted playing alongside such a talented midfielder.

Ozil and Alexis’ link-up play is a deadly combination for the Swans to deal with. On a good day, it is nearly impossible to stop them. Swansea will be praying for an off day from the two Arsenal stars.

Petr Cech

The presence of the giant Czech no doubt boosts the confidence of the defenders playing in front of him, knowing that if Swansea get behind them, they still have to get past arguably the greatest goalkeeper in Premier League history.

Cech has saved Arsenal many points since his switch from London rivals Chelsea, and Arsene Wenger will hope that this continues for at least another season.

David Ospina is a great shot stopper, but there is simply no way Arsene can keep Cech on the sidelines.
