Former Chelsea midfielder Deco has risked irking the Stamford Bridge faithful by saying he wants Manchester United to win the Premier League.
Former Chelsea star Deco says he wants to see Manchester United win the Premier League under Jose Mourinho this season.
The 39-year-old spent two years at Stamford Bridge, winning the league title and two FA Cups under managers Luiz Felipe Scolari and Carlo Ancelotti.
But the former Portugal international has given his backing to Mourinho, under whom he won the Champions League with Porto in 2004, to guide United to the title this term and restore some "pride" at Old Trafford.
"When Jose is at a club, everyone is looking at him," he said on Wednesday. "I think he is the right man for the job.
"United need to bring back the pride of the club and bring back the victories and titles. Jose Mourinho is the man to do that.
"The Premier League is tough. A lot of new players need to know each other, it's complicated. They will improve and fight for the Premier League for sure.
"The expectations are so high and they invested a lot. Everyone is waiting for something good from United. From my perspective I hope Jose can win the Premier League with United like he did with Chelsea.
"Different players and a different club. You don't change everything, you need to adapt in a new club. This is normal."
Deco is confident that Antonio Conte, who took charge at Stamford Bridge after guiding Italy to the Euro 2016 quarter-finals, can bring success back to Chelsea despite the increased competition in England's top flight.
"It's normally difficult for all the clubs when you change managers," said the former Barcelona man. "He is a very good coach, he won everything at Juventus.
"He will bring new ideas but I think the Premier League is more difficult than before. The level has improved a lot. It is very hard to win games. I think it is normal.
"They have got Conte to bring the club to a high level again. They will try to win the Premier League and qualify for the Champions League but of course Chelsea need to fight for the title every year."
