As for the squad, think Roberto has said already we'll need 6 players to cope with the demands of European football. Whether that means on top of what we've got (doubtful IMO) or he's taking into consideration outgoings I'm not sure.
IMO we need to loose alcaraz, guaye and vellios. We then need to add...
CB - Martins-indi, and promote/use a couple of youngsters in the squad.
RB - Seamus can't play every game! Maybe stones will offer the backup to him, although I see him as a CB now. Micah Richards could be a good addition for both CB/RB
CM - I have no doubt Barry will be back, add Gibson in there with McCarthy and Ross's ability to play there, plus that little whipper snapper ledson who I can see making a step up next season...adding 1 more for reasonable money could be the tactic. Maybe a diame or simlar type available for similar cash.
ACM - Ross, Osman and Naismith have all done a job there this season, even Mirallass has at times. Really not sure if he'll go all out and buy a dedicated player for that posistion. Maybe a squad addition offering a option there as well as elsewhere. A better younger Osman? Holtby could be a good addition IMO.
Winger - Think Del will be back again on loan and with pienaar, McGeady and mirallas I don't think he will or needs to do anything in the summer. Maybe in January depending on performances.
CF - I have no doubt we'll buy 1 big striker. Whether that's lukaku, bony, Remy or whoever. It's a must!! I also think it's nailed on Traore will be back on loan, confirmed by bobby keeping him whilst injured, kone will be back and Naismith and mirallas also provide an option.
In - Richards, martins-indi, Diame, Holtby, Lukaku. (Traore) (Delefoe)
Out - Alcaraz, Duffy, Gyaye, Vellios.
That would be some squad with those additions.
