Everton have been accused of making a 'derisory' bid for Matthew Kennedy by Kilmarnock boss Kenny Shiels.
The fee offered by the Merseysiders for the 17-year-old Scotland youth international is believed to be lower than the £250,000 reported which has angered Shiels.
The Killie boss confirmed defender Jeroen Tesselaar, who went off with a hamstring injury in Tuesday's 2-1 League Cup defeat by Stenhousemuir, would be "out for six weeks".
But on the prospect of losing one of his bright young prospects for good, Shiels said: "There are all sorts of rumours going around but at this moment he is playing for me on Saturday.
"They (Everton) have made a derisory offer which was disrespectful to the club and unsettled the player which I wasn't happy about.
"But that can change as you know and if we were speaking tomorrow it might be different but hopefully it won't be.
"I spoke to him and he is okay."
Shiels was also surprised with recent reports linking Rangers with his goalkeeper Cammy Bell.
"I find that hard to believe," he said. "It is a bit late, isn't it? There's not been a thing (from Rangers).
"If they were wanting him you would have thought it would have happened maybe a week ago but I can't see it happening now."
