Ron Vlaar has revealed he could yet sign a new deal with Aston Villa this summer.
Liverpool have declined to comment on reports midfielder Jordan Henderson has signed a new five-year deal at the club.
Crystal Palace boss Dougie Freedman believes possible suitors would be getting striker Wilfried Zaha 'cheap' for £11million.
The striker is enjoying a fine season with the Eagles in the Championship, including netting four goals in his past two matches.
Premier League sides Liverpool, Manchester City and Arsenal have been linked with the England Under 21 international, who has been tipped to make a move in January, with a fee of around £11m mooted.
But Palace boss Freedman reckons his starlet is worth a lot more than that and he hopes the striker will stay and play Premier League football with the Eagles.
He said: "I know he is worth more than £11m. You're getting him cheap if you get him for that.
"Wilfried has dedicated himself to the game and is heading in the right direction. We give young players the chance to play and that's what he is doing now.
"It's a matter of time until he plays in the Premier League and let's hope that is with Crystal Palace.
"As we speak right now he's on a long contract and he's very happy."
