JOHN HEITINGA’S Everton future remains uncertain after David Moyes admitted he was aware of clubs contemplating a move for the Dutchman.

And although having not received any formal offers for Heitinga, the Goodison manager has refused to rule out the player departing in the January transfer window.

Reports in Germany suggest both Bayern Munich and Wolfsburg are tracking the Holland international, who was receptive of news from the former’s interest.

Heitinga further fanned the flames of speculation this week by declaring he would like to return to former club Ajax at some point in his career.

Moyes revealed last month he had urged the 27-year-old to regain his focus after a series of disappointing performances since returning from starring for his country in the World Cup.

Heitinga has completed a full 90 minutes in the Premier League only once this season and was substituted at half-time in last Sunday’s 2-1 home defeat to Arsenal to avoid being sent off after an early booking.

And when asked if Heitinga could leave in January, Moyes said: "I don’t know. We have had no offers, but you hear bits of rumours like everyone else. There has been no official contact from anybody regarding Johnny Heitinga.

"I think his character and type is one who will battle for his place, and I have no reason to think anything other than it (the interest from other clubs) is just speculation.

"I haven’t heard from Johnny or any clubs. He has to get on with it. There is competition for places and he is involved in that. Will I cash in January? I don’t know."

Moyes, meanwhile, has weighed into the ongoing club versus country debate by suggesting players may have to forgo their wages should they be called up for international duty during the domestic season.

Everton will be without Tim Cahill for as much as six weeks when the Australian represents his country in the Asian Cup, which runs between January 7 and 29.

And while accepting there is unlikely to ever be an ideal solution to the issue, Moyes believes cash-strapped clubs may be tempted to stop paying players when on duty in such competitions.
