A false report appeared on the website yesterday evening claiming club chiefs had decided to release Kuranyi from his contract at with the Bundesliga club.

Schalke have moved to rubbish the report and the club's managing director told the Bild newspaper: "That is absolutely not the case. At Schalke nothing like this has happened.

"We now have to clear up what was wrong with our homepage."

According to reports in Germany, the rogue message was the work of internet hackers.

The website was closed for maintenance this evening.

Kuranyi has endured a disappointing season. He has been criticised by Schalke fans for his performances and has also been frozen out of the Germany national team after last year walking out of a match at half-time when he was not named in the matchday squad.
