Aberdeen have knocked back further approaches from Nottingham Forest and Queens Park Rangers for Scott McKenna – but Derek McInnes remains unsure if he will be on the plane to Rijeka.
The two Championship clubs followed up their initial interest in the Scotland centre-half but it was not enough for the Dons to consider selling.
QPR have now reportedly moved on and are instead pursuing former Rangers defender David Bates, who is at German side Hamburg.
Clubs in England have until Thursday to purchase players – the same night Aberdeen face Rijeka in Croatia in the first leg of their third qualifying round tie.
McInnes said: “There was a fresh offer. I don’t know if there was a written offer from Nottingham Forest but there certainly was from QPR on Friday but clearly it was not enough. It was a slight increase and it was structured in a certain way but it was not enough for the club to accept.
“Scott’s had a lot to contend with but his performances have been great.
“It’s up to the buying club to make my chairman think differently but as it stands Scott will remain with us.”
McKenna has started all five games so far this season and if available, would expect to start in Croatia on Thursday night.
Mikey Devlin and Ash Taylor remain sidelined but Greg Leigh has come through his second game back without any problems following an ankle injury.
McInnes said: “I hope I can get a few more people out of the treatment room. Now we travel out to Croatia on Wednesday and another huge effort is required.”
The Dons came from behind to beat Hearts 3-2 yesterday, with two goals in the last 10 minutes from Sam Cosgrove and Ryan Hedges. Cosgrove gave them the lead in the first half before Steven Naismith and Jamie Walker turned the game in the Jambos’ favour.
McInnes added: “The crowd helped – they responded to the quality and effort of the team.
“They had an appreciation that a lot of my players were running on empty.
“We’ve always had teams that score late winners. It can be worth 12 or 15 points a season.
“It was a really good afternoon and Pittodrie was at its best in the sunshine with the fans going home happy.”
