Arsenal boss Arsene Wenger, who shared a flaring rivalry with his Manchester United counter-part, has paid tribute to Sir Alex Ferguson, who retired from his managerial position two days ago.
"I would just like to pay tribute to an unbelievable achievement and a fantastic career," he said on Arsenal.com.
"Basically the achievement is immaculate, when you look at the whole structure and consistency of the achievement. It is, of course, something exceptional.
"It is difficult to imagine English football without him, but it's now a reality and a fact. Of course the next manager has to fill in and show he has the dimension to do that. It is a big task for the guy who comes in."
Arsene Wenger was also appreciative of Sir Alex Ferguson's hard work which was important in establishing Manchester United as one of the best run organisations.
"They have developed very well and they are in a very, very strong position to deal with the problem they face.
"What you can say still is that Manchester United are commercially and financially one of the strongest two or three clubs in the world, and that is still a good basis to start when you come in because you know the players are there, the team is there, and the potential is there," he said.
Wenger also believes that it's a really tough job to replace Sir Alex despite the strong squad, he further added:
"Of course it's a great void to fill for Manchester United, because the charisma and personality disappears suddenly in a club which has been dominated by it for such a long time. It's not an easy task to replace a person like that."
David Moyes who will be the boss at Old Trafford next season will surely face a tough job at hand. Whether he will look to create another formidable rivalry with Wenger remains to be seen, however.
