Deco has backed his former Porto and Chelsea manager Jose Mourinho for the top job at Manchester United.
Former Chelsea midfielder Deco believes Jose Mourinho is capable of taking Manchester United back to the Premier League summit.
United - 21-time league and three-time European champion - has struggled to recapture past glories since the retirement of Alex Ferguson in 2013, with David Moyes and Louis van Gaal failing to win major trophies at Old Trafford.
Van Gaal's men are struggling this season, fifth in the Premier League and six points adrift of the fourth and final Champions League qualification spot.
