Agree with qs on this - he's not good enough for us, no buggy even if goes to Utd. I don't entirely agree though: if their defense is calamitous, he actually could improve them even if it's not as good as ours. But in the bottom line there must be a reasonable line where the great fear of selling to our direct rivals is checked.
And of course, selling means replacing. We were fucked in the past, sure, but some basic assumptions are beyond debate. If he's sold without replacement, it's a whole other issue (got nothing to do with TV or selling to a rival, etc.).
