Jose Mourinho has backed Louis van Gaal to turn around Manchester United's form this season.
The Dutchman was placed in charge at Old Trafford after David Moyes was fired midway through the 2013-14 Premier League season, but is yet to record his first league win at the club, while the team has already been knocked out of the Capital One Cup.
The Chelsea manager, who was part of Van Gaal's staff at Barcelona, told Eurosport: "He is one of the best managers in the world so I think he is a man with great experience for the job.
"Manchester United is a big team [and] he is a big manager so I think they will do well together."
United sit 14th in the Premier League table.
