Maarten Stekelenburg has confirmed he is considering a 'fantastic' offer to stay at Ajax, but accepts it would be 'insane' not to want to play for Manchester United.
Holland No.1 Stekelenburg has been mooted as a leading contender to replace compatriot Edwin van der Sar at Old Trafford next season when the 40-year-old retires.
Atletico Madrid's David De Gea is rumoured to be United's top target, but reports claim Van der Sar has recommended Stekelenburg as his successor.
Stekelenburg, who has also been linked with Schalke as a replacement for the Bayern Munich-bound Manuel Neuer, won the Eredivisie with Ajax at the weekend.
He has received an offer to stay with the newly-crowned Dutch champions, but also acknowledged the lure of playing for their Premier League counterparts United.
"I have received a fantastic offer from Ajax which is under consideration," he told NUsport magazine.
"There has been nothing else, zero. Maybe because I have been injured."
But he added: "Anybody who does not want to play for Manchester United would be insane."
Stekelenburg has one year left to run on his contract at the Amsterdam ArenA, but says he is in no rush to finalise his future as he waits to see if other offers materialise.
"I wanted to see how things develop," he said. "Nothing has happened, so I will talk with Ajax. I have had a fantastic time here and I have great respect for the board.
"I have always been treated very well. They have made a fantastic offer, and a second meeting is scheduled. But it has to do with whether anything else might come my way."
