The City boss has also said there is plenty of motivation for the City squad to perform...
Coventry City manager Steven Pressley has revealed no decision has been taken on whether to extend Mark Marshall's contract beyond the end of the season.
The City winger has started the last two League matches for the Sky Blues and assisted Carl Baker when he equalised against MK Dons in the 2-1 defeat at Sixfields.
The City boss has had plenty of options in midfield over the last few weeks but Marshall will be in contention to start against Peterborough United at the weekend.
Whilst Pressley has praised the impact the 26-year old has had, the City boss has confirmed no decision has been taken yet.
The City boss said: "It is all still up in the air. I think in the last couple of weeks, he has been a breath of fresh air.
"We've been working really hard on certain aspects of his game as I still think there are improvements which can be made.
"But the one thing about him is that he is a player that wants to improve. He has completely brought into the work ethic at the club which is often difficult to do.
"It has been a real culture change for him but he is a real good lad who wants to do well which makes working with him much easier. In the last two weeks, he has certainly been one of our better performers."
The Sky Blues are currently 13th in the League One table, six points from the relegation zone with five games remaining.
Despite the mid-table position, Pressley believes there are plenty of motivations in the dressing room to do well from now until the end of the season.
He added: "We've got players here who have long-term contracts and I'll imagine, players who want to be part of bringing this club back to where we all believe we belong.
"They have to prove every day that they're ready for the challenges ahead. You've got players who are out of contract and they have to prove to me that they're good enough to take forward.
"Everybody has got a motivation at this moment in time. When your a footballer, your main motivation should be to win football matches and as many as possible.
"I want players in this club who take real pride in their performance and now is the best time to see who those players are."
