Alan Curtis plans to pitch Jonjo Shelvey into Swansea's FA Cup tie at Oxford amid reports that the England midfielder could leave in January.
Playing Shelvey at the Kassam Stadium would cup-tie the 23-year-old if he were to move on in this month's transfer window, but Swansea boss Curtis has again insisted he wants the former Charlton and Liverpool midfielder to stay in South Wales.
"It's fair to say that Jonjo will play on Sunday, and hopefully he will show everybody what he's capable of," said Curtis, who takes charge in a permanent capacity for the first time after being promoted from the caretaker role he had held since Garry Monk's departure on December 9.
"From there we will look at it in terms of the league fixtures to come."
Shelvey has only started once in Curtis' five games in charge, with Crystal Palace and Newcastle are reportedly keen to recruit the six-times capped international.
But Curtis said he told Shelvey as recently as yesterday that he wants him to remain at the Liberty Stadium.
"I would want him to stay, yeah, absolutely," Curtis said.
"I spoke to him (on Friday) and told him that. I feel that he's got a huge part to play.
"He's not in the team at the moment and there's always going to be speculation about good players.
"Jonjo's a current England international, so there's going to be speculation about him moving on.
"We feel that he's a huge part of what will be a difficult run-in."
