Derry City boss Stephen Kenny is resigned to losing star man James McClean.
Peterborough United have tabled a new bid for the midfielder which could net Derry up to £350,000.
But Kenny wants to delay any deal until after the completion of the League of Ireland season later in the year.
"To lose our best player would be a massive blow," said Kenny.
"It would hinder us in a major way so the club has to make a decision based on that. We don't want to stand in James' way. He's an outstanding player, a brilliant person, has a tremendous attitude and deserves an opportunity.
"From my point of view, that would be preferable in October rather than August. I wouldn't feel his value would depreciate between August and October."
McClean was one of the star turns in Derry's win over Shamrock Rovers before the television cameras last Friday night which brought them right back into contention in the title race, ahead of their trip to Bray Wanderers this evening.
