Harry Redknapp believes that Sir Alex Ferguson is the best manager in football - better than the "Special One".

Writing in his column for The Sun, Redknapp declared: "There is no doubt that Mourinho is catching up with Alex Ferguson as far as reputation and achievement go in management."

"They are my one-two in the managerial world."

Ferguson is still miles ahead in Redknapp's opinion.

"Fergie is king of the castle in England particularly. Mourinho has not got close to what Old Trafford's emperor has won in the Premier League."

There was an important rider attached to Redknapp's assessment though.

"But it [Ferguson's achievements] has all been done in one country. Mourinho would have stayed at Chelsea had there not been a big fall-out with owner Roman Abramovich.

"Yet that dramatic exit inspired him to go to Italy, where he has now added a Serie A crown to the Premier league and could well add another. "

Commenting on Mourinho's future, the Tottenham manager firmly believes that the Portuguese is headed to Spain.

"I also believe Mourinho will end up going to Spain to manage Real Madrid and become the first person to win a league title in all three countries.

"Winning the Champions League with Porto was also an incredible feat. They are good but you would never really have the Portuguese team down as winners of that tournament.

Continuing on the Mourinho-Ferguson theme, Harry wrote:

"It is incredibly difficult to compare the two men, as, in essence, they belong to different eras.

"Ferguson is part of the United furniture. He has steadily built his teams and combined a fantastic youth policy with big signings.

"Mourinho almost has the kit-car approach. He turns up, drills his team to play and behave the way he sees fit and makes them overnight contenders.

"Longevity may not be his motto but in the modern times, with a rapid rollover of coaches, he is a master.

"Mourinho has time on his side, too, to try to overtake Ferguson. But right now, I think my opinion that United would beat Inter says enough about both men.

"I was at Stamford Bridge on Tuesday and you could sense the Mourinho effect around the place before kick-off. The fans still love him and he is hugely revered and respected.

"Those supporters need to move on now, back Carlo Ancelotti, fondly wave goodbye to Mourinho and set about trying to win next season's Champions League.

"I thought this would be their year but one thing cost the Blues dear against the Italians.

"The absence of Ashley Cole was clear. He is vital for Chelsea and England."

However, despite beating Chelsea comprehensively, Redknapp does not see Inter lifting the Champions League crown.

"I do not see him winning it this season and I think they would lose over two legs to Manchester United if the teams get drawn together tomorrow for the quarter-finals.

"At the moment, United have too much flair for Inter to handle.

"They also have Wayne Rooney in such amazing form that he is virtually unstoppable - especially by the Italians."
