Barker, who has scored 22 goals for the Stags this season is hoping to entend his Stags career "I understand that the chairman and the manager have got to talk to those who are out of contract in the summer first," he told BBC Radio Nottingham.
"Then hopefully they'll talk about extending other people's contracts."
"Once you get into your last year, people start talking about Bosmans, and nobody likes being a couple of months away from being out of contract,".
"So it'd be nice if they came to me and asked if I wanted to stay a bit longer."
