The injury to the Arsenal and Wales midfielder Aaron Ramsey has forced the hand of Arsene Wenger a little, even though the Welshman is back in training I do not think Wenger can take any risks.
With Ramsey having been played on the right in recent games though, the manager has got a few options in the Arsenal squad, with Theo Walcott clearly one of them. But I feel that he will go with Jack Wilshere, just as he did when making the change against Hull City last Monday.
Wilshere is much more similar to Ramsey and so the system and style can stay the same with just a different player. I think Wenger will make a change at left back as well, bringing in the extra pace of Kieran Gibbs to cope with Swansea´s Nathan Dyer, while the Englishman adds a bit of attacking threat as well and this is a home game.
Apart from that I expect the same team that has been doing so well and although the Welsh club are a good side and are in good form, I cannot see anything but an Arsenal win tonight.
