Everyone is forgetting two other players we have who are possibly up for sale. One being Negredo - £15-20m (wants to leave) the other being Jimmy £15m who also may wish to leave. The club will have to decide what to do on the others. Rodwell will get around the £10m mark, most clubs will feel he can make a contribution, he hasn't been injured in a while now, he just hasn't played and if he passes a medical another club may feel he is worth a punt.
Promoted teams who have some cash to splash may feel he is worthwhile, Garcia as well looked very solid and comfortable on the ball at the end of the season, foreign clubs would probably offer £10m for him. We are in a position whereby we could sell a lot of players to bring in 2 big names.
I think the Juve stuff is Tolmie expressing his wishes in terms of the clubs transfer dealings. Barkley seems more realistic with our need for English players. We need to change the clubs identity to supporting homegrown talents rather than stifling it - as is the mass opinion because of Johnson, Rodwell, Richards, Milner etc (poorly educated opinion I would add).
I am not too concerned about us adding Vidal or Pogba, if we keep Yaya then we will be fine for a couple of seasons and those two have one recently emerged as top players... there will be others. With Fernando and Fernandinho, and indeed Zuchulini we have a mix of youth and experience, and a lot of dynamism in that midfield that a Barkley or creative player will thrive on.
