Manchester United boss Sir Alex Ferguson is happy for Rio Ferdinand to take on FIFA president Sepp Blatter over his racism comments. Ferguson has been a long-time critic of blundering Blatter but believes his apology over controversial remarks about racism in the game should be accepted.

He said: "Sepp Blatter has apologised and that's fine. That's appropriate and that's where it lies for me. It's always nice to apologise."

Ferguson had no problem with United's Rio Ferdinand having a tweeting row with Blatter.

Last night Ferdinand returned to the attack on Twitter. "Gus Poyet ...drop me out...what age are we living in here. Some prehistoric talk I'm hearing," he tweeted.
