Manchester United manager Ole Gunnar Solskjaer says his team must spoil Adnan Januzaj's return to Old Trafford.

Januzaj burst onto the scene with United under David Moyes in 2013, but lasted only four more years at the club before joining Real Sociedad.

The La Liga leaders have drawn United in the Europa League last 32, and Solskjaer knows Januzaj will be relishing the tie.

"They're hard-working with high intensity and some high-quality players and they've got our own Adnan of course," Solskjaer said. "They also have some experienced players and some young, up-and-coming players.

"Everyone who plays against Man Utd wants to show what could have been and Adnan's done well in his career.

"It's always difficult to see where you're going to go after Man Utd and he's one of those boys that you hope would make it here. It wasn't to be so now we'll have to make sure that he's not going to enjoy his return!"
