Tottenham Hotspur manager Harry Redknapp believes that Inter will falter if they run into Manchester United in the Champions League.
The Nerazzurri coach Jose Mourinho recently masterminded a victory over old foe and current Chelsea boss Carlo Ancelotti, which dumped the Stamford Bridge club out of the European competition.
The manner of the victory over the Portuguese tactician's former club earned him several plaudits, but Redknapp remains convinced the Biscion boss still has some way to slither before being spoken of in the same breath as United counterpart Ferguson.
"Jose Mourinho may be the self-appointed 'Special One' but he is not yet 'The Greatest'," Redknapp wrote in a column for The Sun.
"Fantastic result and performance by Inter Milan on Tuesday night to knock Chelsea out of the Champions League.
"But 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.
"That brings you on to the debate on the two managers.
"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.
"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."
The outspoken manager has been linked with a move away from the San Siro in the recent past, with Manchester City, Liverpool, and Real Madrid being spoken of as likely destinations.
"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," added Spurs' gaffer.
"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."
