Manchester United hero Nicky Butt has defended Sir Alex Ferguson after their derby defeat.

Butt insists Ferguson would've found the players capable of making the difference at United - if they were available.

"If they were there and available, the manager would have bought these players by now," said Butt.

"He has money to buy players but he won't spend it on someone who can't improve the team.

"You do need to look at replacing people like Paul Scholes and Ryan Giggs but I can't see who is going to do it."
