I've been reading the articles by German press/journalists on twitter and around the net and it seems they all seem to think that similar to Modric, although he started out as a no. 10/winger, he has lately been played as a deeper-lying play-maker in central midfield, which is where is long-term position and skill-set are seen.
So I guess Holtby is going to be our play-maker, meaning I think Moutinho will be left as being just too expensive. I can't see any more recruits for central midfield slots. Assuming AVB does want to go to 4-3-3 eventually I see the starting midfield 3 being Sandro, Dembele and Holtby, with Parker, Sigurdsson, Dempsey and Carroll providing more than adequate back-up. I think Thudd/Jenas/Livermore will all be gone.
I feel funds will be concentrated on the front-3 positions, especially if we end up losing Bale.
