Mourinho, who won the Premier League with Chelsea in 2005 and 2006, has made his desire to return to England clear after he finishes his job in the Spanish capital. The former Tottenham boss is confident that Mourinho's winning mentality makes him the right man to succeed the Red Devils icon, who reached his 26th anniversary in the Old Trafford dugout in November.
Given Ferguson's vast trophy cabinet in more than a quarter century in charge at Old Trafford, the ex-Spurs manager noted that it would be a daunting task for any successor, making Mourinho more of a unique candidate to take it on successfully.
"Attempting to manage this great club has broken many managers. Look at when Sir Matt Busby left Old Trafford. The likes of Frank O'Farrell and Wilf McGuinness really struggled as it was virtually an impossible job," Redknapp said. "Taking over from Fergie, whenever it happens, will also be almost impossible, but Jose could once again be the Special One. If anyone could do it, he could, and United fans would love him."
