9 goals and 6 assists in 38 La liga games to me doesn't really suggest he's worth £9m. You can get Nasri for less and his role is looking more important this year. Although that said I don't like using City players as Mancini loves to rotate.
I'm still optimistic about Kagawa mind. The only problem is that he's very, very selfless and I can see him being the third to last man to touch the ball in goals a lot too. Without Rooney I'd expect him to do well, behind RVP. I took him out mind I think, to do exactly what you did -- pack the midfield with goalscorers. There are a lot of affordable ones.
Im going to go with Santi mate, hes playing in the old Fab role and ive watched him closely since he joined them and he is going to be key, one thing you can rely on Arsenal for is attacking returns and this guy will be involved in everything. Like i say hes playing almost a second striker with the freedom to do what he wants. He also got a goal and two assists fro Spain in the week.
I brought Kag in GW2 as i thought he would do well, im sure he will when he plays but im not sure he will play every game like Santi 8.5mill is to much to rotate - i heard he picked up a back injury fro Japan as well.
I wouldnt go near Nasri tbh, it will be all change once Barry is back IMO and Silva will be unleashed with Agureo and Tevez, only nailed on starters for City are Yaya, Aguero, Hart, Kompany.
Trying to find a way to bring in Adam - honestly.
The deceptive thing is a lot of midfielders are actually playing as strikers, Mofro, Hazard, Carzola, Nolan, Dempsey etc. If you pick 5 midfielders who are likely to score 10+ a season you'l be alright.
