Eh? Ronaldo being sold was a great deal, firstly, 80mil wasn't superb value commercially and quality of the player, 80mil isn't "expensive" for a guy like him, he'll rake in shirt sales, sponsorship, fans like almost no other player on earth, ever, 50 goals a season he'll be instrumental in them winning titles again.
But Utd have serious debt, they needed a large chunk of cash to buy in replacements for 3-4 aging members of the squad, those purchases were just delayed a couple years. Sure you could have Ronaldo now, but you'd have no money to replace Scholes, VDS, Giggs and a couple of others.
I said on these forums, the money for transfers is NOT the issue 2 years ago, they are waiting for retirements then will spend big.
its not about how much cash you have in the bank to spend on transfers, its about weekly incoming and outgoing cash. With Scholes, VDS, Neville, Giggs, and whoever else leaves over the summers wages off the books, that money can now go on the wages for the replacements.
I've said for ages that when Utd have a big "retiring" season they'll buy replacements on a fairly big scale, they were just waiting for wages.
Transfer money isn't an issue, they can buy a central midfielder aswell, its not an issue. However, anything could happen, system change, always a 4-4-2, two dm's and one ultra attacking player like Young as the other central midfielder.
Also still find it weird that Utd fans keep going on about how Nani/Valencia is fine and young = more than enough cover........ can Utd fans do maths, 2 positions, one player gets injured for a season, like Valencia, and you are down to two real wingers, with no cover/rotation ability.
Two wingers is never enough, 3 is the bare minimum you want, and 4 gives you proper cover. Considering two of those guys actually like playing as a withdrawn striker, then some games they can sit out, some they'll play on the wing, and some they'll play upfront.
I assume you didn't see the game against Barca where he was fouling people left right and centre then
