It's difficult for me to predict anything because I haven't seen much of Sporting this season, to be honest. The last time I saw them play Paulo Bento was in charge, so I'm sure Carvalhal will have changed things around a bit, in terms of style and formation.
I'm looking forward to the game, I think we'll finally get to show what we are about in Europe with a proper squad of players to pick from. The games against Benfica wasn't a true reflection of this team. Hopefully Osman and Arteta play like they did against Chelsea because both players will revel with the extra time and space on the ball European games allow you to have.
I'm a little be worried about a back four without Johnny Heitinga, that's one thing I'd say. Senderos has something to prove though, so hopefully he steps up to the plate. I'd probably with a similar team to the on against Chelsea but with Pienaar and Senderos in for Heitinga and Bilyaletdinov.
