I share your concern also man, i also have concerns that we will not only just buy 1 CM, but only 1 CB aswell - that to me, is pure madness if that happens.
We could have won the league this season if we'd bought quality 2 CB's & 2 quality CM's imo - Arsenal & City fans could say the same thing too. The games we lost were predominantly down to us being pussies in midfield & in defence & havin players out injured, with no like-for-like cover.
Its pretty plain to see, that we only tick when Carrick's playin too, which means we're a one-trick pony / one-man team. His presence in our team is immense, but i dont doubt the club know this & i hope to God they find quality back-up / someone to compete with him for a starting role. Its an absolute must!
The two CB's on my wishlist are Gundogan & Strootman. I've no doubts over Gundogan's fitness tbh (he just needs a summer rest & then a full pre-season), but Strootman is another kettle of fish. So much for knee injury's not being as critical as before, with the advent of improved science & surgery techniques etc.. Maybe players are rushing back too soon or the clubs are pushing them too hard in their recovery.
Strootman is the dynamic type we need in CM. Pure box to box all day long & loves his battles. Of course his transfer to us seems very unlikely, due to his breakdown & Cartilage damage surgery in Feb, but i'd be shocked if LvG wasnt monitoring his progress thus far, because he would have him at United already, if not for his injury.
We've seen that United arent willing to take any chances with crocked players ala Vidal, last summer, but that's the type of player we need - aswell as a Gundogan type.
We seem to be jinxed with world-class box-to-box targets - they end up with snapped knees. If i was a player in that category - i'd be prayin United weren't interested in signing me. I reckon Hargreaves has put some voodoo-like curse, on all dynamic CM's we're interested in - as he's blamed us for his knee injury problems (wanker)
