Manchester United boss Sir Alex Ferguson expects Chelsea to challenge next season - if Jose Mourinho takes charge.

Ferguson dropped a big hint he expects the Real Madrid coach to move to Chelsea in the summer.

"You'd ­expect - if Jose (Mourinho) goes back to Chelsea - a big challenge there. And City won't go away either. Arsenal will ­improve," he said.

"There's some indication Arsenal are building a better squad that people think. And Tottenham have been progressing for a ­couple of years now, so it's going to be a hard league to win.

"We just need to concentrate on winning the league this year, but things are looking good."
