Van der Vaart has established himself as a key member of a Spurs team that has secured two top-four finishes in three years having joined the club in the summer of 2010 from Real Madrid.
However despite finishing in the Champions League qualification spots this term, Spurs will feature in the Europa League after Chelsea took their place by virtue of beating Bayern Munich in the competition’s final earlier this month.
While the 29-year-old has previously insisted Tottenham’s lack of Champions League football would have no bearing on his future, the Daily Mail reports he is considering an approach from Schalke for personal reasons.
His wife Sylvie is based in Cologne and works for German television station RTL, meaning a switch back to the Bundesliga may make sense for the former Hamburg player.
It is reported that representatives from Schalke have already made contact with Van der Vaart’s agent and that the player himself is open to the prospect of switching clubs.
Van der Vaart has around two years left on his contract at White Hart Lane and was quoted in April as saying he would not be leaving the north London club anytime soon.
Speaking before Chelsea’s win over Bayern, he said: “Even if we don’t manage to get into the Champions League, that is no reason for me to leave.
“Any young player wants to play for Barcelona, Manchester United or Real Madrid. But that is something I’ve done, and I am now happy at Spurs.”
