Some of the replies are here are stupid. Do you really expect us to win the title after City with already the best squad in the league added quality players so much so they have Aguero on the bench! Idiotic. Jose has us in a final and 2nd with a guy from Fulham who can't get into the England squad in defence, a failed winger best known for catching bird droppings in his mouth as well as the worst RB out of the top 10 who uses one leg to smash balls into shins. I'm not saying we have to better City's spending just wait until we bring in a few more signings so Jose can have a starting 11 closer to what he wants from his players. Some of you need a reality check.
The reality check is that Jose signed a defender thats been bunk and cant displace that defender you mentioned, and has already had what, 2 or 3 windows to address the fullback situation, his poor handling of the Luke Shaw situation this season hasn't been great either.
The fact is if we'd been going after reasonably priced players to fill actual gaps in our squad we'd be better off, but as has been reported we'd rather chase players like Perisic to the bitter end, not only willing to overpay but chasing a fruitless endeavour when other signings were happening around us, there needs to be more flexibility than that.
The RW situation is particularly annoying when you take into consideration the Sanchez signing, when everyone thought he'd slot in there and not displace Martial instead, who now looks likely to leave, which is a big mistake in itself. We already need 2 midfielders as it is and to address the fb situation as you mentioned, are we going to splash out on a RW as well? Highly doubtful, suffice to say I think mainly everything has been handled quite poorly in this regard but maybe thats just me.
I drew up a list of about 8-10 players we could of signed in the last 2 years since Mourinho started that would of dramatically improved out squad overall, all within the budget of what we've already spent, so it can be done, it just hasn't, and so i dont have the confidence that it will happen. I expect more short sighted signings with the next 2 odd seasons in mind, and not the future, where Mourinho won't be with us.
Another reality is overpaying and begging Fellaini to stay when what he brings to the table we could get from any lanky player. No other top team in world football would ever beg a player of such limited ability as Fellaini.
