Greek Super League club AEK Athens have revealed that Everton have not yet made an offer for Kostas Manolas.

The 20-year old centre-back, who is out of contract in the summer, has emerged as a target for the Toffees but AEK's director of football Arnar Gretarsson insists no bid has been put forward.

"I know that Everton is interested in Kostas Manolas," he told

"They follow the player and there is a serious interest but nothing official so far.

"Their scouts came to Greece four times to see Kostas. I remember that in the last few weeks they sent a scout to see Manolas against Anderlecht and the assistant of David Moyes to see him at the league game against Atromitos.

"So far, we don't have any official talks. It's in their hands to make an offer and start negotiating. They know what we are asking to sell him.

"I spoke with the agent who has the mandate from Everton but I didn't speak so far with someone from the English club."
