Former Newcastle and England boss Sam Allardyce warns Conor Gallagher about leaving Crystal Palace midseason.

The youngster has been outstanding for Patrick Vieira's team since signing on loan from Chelsea in the summer.

The Blues do have the ability to bring back Gallagher in January, but Allardyce thinks he may be better off at Palace, where he has an easier route to first team opportunities.

Allardyce used the example of Jesse Lingard, who rejected an opporunity to stay at West Ham after a successful loan spell and has since failed to play regularly at Manchester United.

He told talkSPORT: "Well I wouldn't spend too long there if I don't get into the first team [Chelsea].

"I'd want to come back and give it a go and I think on his form at the moment and you have to bear in mind now he made his England debut, he's an England international.

"He would want to go back and try and get in the team but I think if you do that, you've got to play enough first team games because if you don't you can easily fall backwards like Jesse Lingard.

"Staying at Man United I think has been a bad choice for him because he's not been selected.

"While at West Ham he was one of the best goalscoring midfield players in the Premier League in his time there now he's sitting on the bench at Man United.

"So you have to be very careful on your choices at the right time and if you're playing as much football as Conor's playing now, and enjoying it more than ever with Palace then you want to continue that.

"If that's not at Chelsea it can certainly be somewhere else in the Premier League I'm sure."
