Rio Ferdinand unsure about something regarding Jose Mourinho

Jose Mourinho is widely believed to have signed a contract with Manchester United.

Writing on Facebook, Rio Ferdinand has said that he does not know whether Jose Mourinho would keep alive Manchester United's rich and illustrious tradition of producing young players.

The Portuguese manager is widely expected to be named as Red Devils boss shortly, having already signed a contract to succeed Louis van Gaal at Old Trafford (Sky Sports).

Of course, the 53-year-old is one of the most successful football managers in the modern era of the sport, winning two Champions League titles with Porto and Inter Milan, whereas he has also won the Premier League on three occasions, across two spells at Chelsea.

As with any manager, Mourinho's players down the years have helped him enormously, and vice versa, but he has often opted for tried-and-tested personnel in the transfer market, rather than exploring his club's youth reserves in an effort to nurture potential gems.

In his final season, Van Gaal employed this policy to some extent in a decision which unearthed striker 18-year-old Marcus Rashford, who may well be named in England's Euro 2016 squad just months after emerging as a prominent figure in Manchester United's first team.

Long before the Dutchman ever arrived, Sir Alex Ferguson was blooding youngsters from United's youth academy and ushering them into the first team, but the club's former defender Ferdinand admits he does not know if Mourinho will preserve that custom when he gets the job.

"Another doubt I keep hearing and being asked is, will he keep in with the tradition of the club which is bringing through the young players? For the moment, I can't answer this, only time will tell," Ferdinand wrote on Facebook.

"One thing I can tell Manchester United fans is that they have got themselves a true winner in all aspects. His CV shows success!"
