I think I misinterpreted what you meant regarding Saul and his passing. IMO his passing is quite good, but not as good as to replace Carrick's. I'm not sure though. I thought Schneiderlin would do better with his passing than he has. So what do I know. Maybe
@Invictus could help out. What do you think of Saul's passing? Would he be able to improve our midfield in that regard or somewhat replace Carrick's passing?
Your 4-3-3 thoughts with Rooney make sense. Good points. Either way it isn't ideal, sadly. I'm not sure what Blind's role will be. It also depends what kind of centre-back we sign. For some reason I wouldn't be surprised if Mourinho doesn't fancy him and he becomes a back-up right away. I wouldn't mind, if he continues his partnership with Smalling for another season and the centre-back we sign gets slowly eased into the side. One way or another IMO he shouldn't regularly start for us, if we want to compete with Munich, Madrid, Barcelona and so on. He definitely should have a place in the squad. At the start of his United career I compared him to O'Shea, a very useful squad player. I don't think there's anything wrong with that. Shaw is a better left-back. We should sign a better or potentially better centre-back and like I said, I'd prefer several central midfielders to him.
