Wigan boss Martinez insists Maloney not for sale
The midfielder is enjoying career best form under Martinez this season.
"Shaun has signed a new contract and has his best years in front of him. He is one of the biggest assets in our dressing room and is a joy to have at this club.
"He is an outstanding footballer wherever you play him. For me, he is the best No 10 in the league.
"You are not going to find another British footballer with the ability he has."
