New Chelsea boss Rafa Benitez has taken aim at Manchester United manager Sir Alex Ferguson.

Benitez reopened hostilities with Fergie yesterday by naming Arsenal's Arsene Wenger as the best manager in English football.

He said: "There are a lot of good managers in the world who have won many trophies.

"When I came to England I knew Arsene Wenger was the best manager who had been here for a while.

"But I can't talk about these things every day.

"I have to concentrate on my team and a very important game against Manchester City on Sunday."
