One Direction singer Niall Horan has reportedly been told by Chelsea manager Jose Mourinho that he can use the club's medical facilities to recover from knee surgery.

Horan and his bandmates first met Mourinho last year when the Portuguese was in charge of Real Madrid.

The Irishman is now being treated by Chelsea's physiotherapists as the pop group prepares to embark on a tour.

"Niall has been welcomed into the club as if he's a Chelsea star himself," a source told The Sun.

"It's the best possible place for him to get the rehab he needs on his knee because he needs to be fighting fit for the band's stadium tour later this year."

Horan's bandmate Louis Tomlinson is said to be close to making his debut for Doncaster Rovers' reserves after signing a contract with the club last summer.
