Czech international striker Jan Koller has admitted that he is tempted to move to the Premiership when his contract with Borussia Dortmund expires next summer.

The 32-year-old Koller turned down a contract offer from Dortmund and will leave at the end of the season.

“A few clubs have been in contact but I have a lot of time to decide,” Koller told Kicker magazine.

“Dortmund’s offer was very good but I felt I needed a new challenge after five years here.”

Koller admits a move to the English Premiership is tempting.

“English football fascinates me,” he added.

“I would love to achieve something in the next two or three years that will stay with me for a long time.”

The towering Czech forward also denied speculation that he was prepared to join Dortmund’s local rivals Schalke 04.

“I would never go to Schalke,” confirmed Koller. “I have promised president (Reinhard) Rauball that I will not join another Bundesliga club.”
