Former West Ham star Trevor Sinclair has questioned Jesse Lingard's ambitions after he rejected a summer exit from Manchester United.

The Hammers were keen to reunite with Lingard after his successful loan spell last season.

But the 28-year-old declined the offer in favour of staying at Old Trafford, where he has struggled for playing time in the current campaign.

"If he doesn't get given the assurances and signs the new deal, then he's not as ambitious as I'd like him to be," former England star Sinclair told TalkSPORT.

"I am confused, why he didn't join West Ham permanently? He was loved there, he was the main man. He played once for Manchester United last season, he played 16 times for West Ham.

"He scored goals, got back into the England squad, why wouldn't he want to sign for them?"
