Manchester City midfielder Yaya Toure believes Manchester United will be weaker next season without Sir Alex Ferguson.
Toure is convinced United will still be a force next season.
But he knows Fergie's departure will be a blow for the champions.
He said: "United are a great club and Ferguson is a big character there.
"He has built everything at United and the balance, I hope, will go to the City side now.
"We will see next year. There will be a lot of rivalry between Chelsea, Liverpool, Arsenal and United.
"Tottenham are coming through and the Premier League is going to be very, very tough."
