Stoke City boss Mark Hughes admits he wants to deal in Bruno Martins Indi.
The defender is on-loan from Porto.
"I think there will be discussions at the end of the season," said Hughes. "They are on-going now to get things lined up.
"I think Bruno has said himself he needs all parties to agree. There's us, there's his club and there's the player himself.
"Clearly he's doing very well for us and we are delighted with what he's doing. Clearly we'd like to get it done if we can and I'm sure we will do our utmost to make it happen."
