In brief:

It'll be interesting to see if Wenger sticks with Bergkamp on the right, which worked so well against Lazio. With Vieira out (the last match of his suspension) that'd leave Parlour free to partner Grimandi in central midfield. Ljungberg will get his reward for the goals on Wednesday, since Pires isn't ready to return.

Man Utd will be missing Jaap Stam, and Fabian Barthez might not be risked since he's not been back in training long.
