He wrote on Facebook: "Congratulations to Jose on being announced manager of the biggest club in the world!
"This is Jose Mourinho's most exciting & most challenging job yet.
"The first thing he needs to do is install 'winning mentality' back into the club. Get this ingredient back into the players but also the people that work inside the club day to day. Give them back that belief so it is breathing throughout the club again, which is so important. But doing the above in the Manchester United way is equally as important.
"I have heard many say the 'Mourinho WAY' is not the Manchester United style of playing football. However, the Chelsea team that Jose put together first time round when he entered the Premier League played with wingers and hurt teams with quick attacking play. They had the likes of [Arjen] Robben and [Damien] Duff on the wings who were direct and quick.
"This is a sign he knows how to get a team playing in a way Manchester United fans can look forward to seeing."Mourinho's detractors have questioned whether he will maintain the club's
sale cheap soccer jerseys tradition of bringing young players into the first team; something he has not done regularly at the likes of Chelsea, Inter Milan and Real Madrid.
Ferdinand failed to address the issue, but insisted the results will improve under the two-time Champions League winner.
He added: "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.
"One thing I can tell Manchester United fans is that they have got themselves a true winner in all aspects. His CV shows success!
"After his recent unsuccessful
Soccer shirts online time at Chelsea in the final year, I can assure you this winner is now a wounded animal which makes him such a mouthwatering appointment. Jose went from winning the League cup &Premier League to losing a dressing room at Chelsea and I am certain he will want to restore all of that very quickly.
"He will be desperate to silence the media who have been writing and saying negative things about him (he will have stored it all being the competitor he is) and will be as focused as ever.
"Mourinho's huge personality is made for this great club, it's what he has been waiting for. Wishing him all the best!"
Meanwhile, Chelsea goalkeeper Thibaut Courtois has backed former manager Mourinho to be a success at United.
Courtois was Mourinho's first-choice keeper as Chelsea won the Premier League in 2014-2015 before the club embarked on a torrid run of form that resulted in his removal as manager at Stamford Bridge in December.
But the Belgium international, 24, believes Mourinho's presence will ensure facing United is a challenging prospect next season.
"He's a very good manager," Courtois told Sky Sports. "Obviously this season it was not our year but I'm confident he's a top manager and Manchester United will be
soccer shirts pro difficult to beat next year."
And Courtois has also backed his own team to bounce back after following up their title win with a shock
Discount soccer shirts 10th-place finish.
"When a big team has
sale soccer jerseys a season like that, everybody learns from it," said the ex-Atletico Madrid shot stopper.
"Not only the players and manager but the directors, fans, everybody. We will be back stronger next year."
