Raul has still not decided whether to sign a contract extension with Schalke, according to the club's sporting director Horst Heldt.

The Spanish striker has proved a hit in Gelsenkirchen since arriving from Real Madrid in 2010.

The 34-year-old's current deal runs out at the end of the season and he is weighing up the offer of a one-year extension.

"There is still no inclination, there is still no decision," Heldt told Kicker.

"For Raul it is a fundamental decision. He has to talk with his family about whether is makes sense or not."

Raul is still a key part of the Schalke side and has started 27 of their 28 Bundesliga games this season, scoring 12 goals.
