Why are people getting their knickers in a twist if there is even an ounce of criticism with regards to Jose? Like you haven't seen his history? Do you really believe he's infallible or that he doesn't make bad calls? Why the sarcasm if someone points something out not to your liking? Remember, Matic is the player he brought on as a substitute only to substitute him 20 mins later. Clearly he didn't think much of him then, so why now is he so hot on him? That's another reason to question his thinking on this transfer.
In any case, I understand where he's coming from - sometimes you need an experienced stop gap - for a reasonable price - not at £50M as it's not prudent. The odds are that we're likely going to have to replace him sooner than later, and in that case, £50M is bad business viewed in that context especially when there are other players out there, possibly younger, who we could get for a lower price. That they might not have PL experience is irrelevant in my opinion - neither does Mendy nor Silva - yet they are generally viewed as very good acquisitions by City. If they fit the bill, then why not go in that direction?
And yes, with a big fat debt and huge overheads, United cannot afford to be spending indiscriminately.
