I disagree. Scholes has looked off the pace recently imo (yes i know it was only a couple a weeks ago that he came back from injury), whereas Anderson has been performing very well for us.
Im not saying Scholes isn't good enough anymore, because he IS. When he's 100% fit and on-form id go with him over Anderson. I just think for a big game like this, against a team that likes to play quick, counter atacking football, we need two CM's that will be able to keep with it over the 90 minutes. Anderson will do that better than Scholes at the moment.
So id go with Anderson without a doubt. Him and Hargreaves were immense at the Emirates when we played there earlier in the season. (as this partnership has been in most games, but especialy at the Emirates & Anfield, very tough places to go)
