Stoke City defender Marc Wilson is urging Asmir Begovic to sign a new contract.
The duo started out at Portsmouth as 16-year-olds and both moved to the Potters in 2010.
Wilson said: "Asmir is a terrific keeper.
"I've seen him since he was 16 and we came through the same youth team together. I even said back then that he was going to be a top-class keeper and he's proving it so far.
"The club would love to tie him down as soon as possible. It's crucial to keep your best players to make those extra strides forward. The manager and everyone in the dressing room would love to keep him for the foreseeable future."
