Ole Gunnar Solskjaer believes Manchester United's acquisitions of Cristiano Ronaldo and Raphael Varane could make Paul Pogba decide to extend his stay with the club.
Pogba has stalled on signing an extension with United and could leave on a free transfer at the end of the season.
"It's up to us now to get results and to prove to ourselves we can win trophies," Solskjaer told a news conference in Bern on Monday.
"Everyone who signs for Manchester United wants to win trophies. To be a part of a winning Man United team, it's the most magical feeling in the world.
"Everyone's just focusing on doing our best and let's see where we go."
