Chelsea's interim manager Rafael Benitez, who was a Merseyside rival of David Moyes during his time as Liverpool manager, said: "He's a good manager."
"I think that he will have a very good team, so I'm sure he will compete at the top and he can win trophies with a big club.
"It's not easy to find someone like Ferguson, but he's a manager with experience in the Premier League. He knows the players, he knows the club and the Premier League.
"It could be a good appointment, but it takes time to say."
