Everton are chasing Molde defender Vegard Forren.
Molde manager Ole Gunnar Solskjaer, the former Manchester United striker, has warned that Forren, 24, will not be cheap.
Solskjaer is aware of their interest and said: "We have in mind that Everton may bid for Vegard.
"There are plenty of clubs who have been to see him many times. We'll see if anyone really wants him if they make a bid. But he will not be cheap."
Forren admits he would be interested in a move.
"Everton are a great club," he said. "I feel ready. I have had many great matches this season and it tempts me to take the next step."
