Anderlecht striker Jan Koller looks set to leave Fulham in the lurch and join Borussia Dortmund, who have agreed to match the London club's £8 million bid and can also offer the Czech star Champions' League football next season.

It was reported last week, Anderlecht agreed an £8 million deal with Fulham but Koller had yet to agree personal terms.

Dortmund had pulled out of the race for the Czech giant because they felt Anderlecht's valuation of the player was too high, but it is now believed they are ready to match the £8 million fee.

On top of that, the German club have now qualified for next season's Champions' League after finishing third in the Bundesliga on Saturday – an event Koller was waiting on before making his decision.

Anderlecht general manger Michel Verschueren said on Tuesday: "We are close to an equal agreement with Dortmund as we know their offer and their financial possibilities.

"As there is already an agreement with Fulham, the ball is in the player's court. He will choose on Friday and we think he will opt for Dortmund."

Both Fulham and Dortmund have offered Koller the same deal – a four-year contract worth £20,000 a week, but Fulham, who won the English first division last season to secure promotion to the Premiership, cannot offer him Champions' League action.

Dortmund had been the initial favourites to land Koller's signature before Fulham stepped in with the £8 million bid. At that point the Czech striker did say that a switch to the Bundesliga outfit would represent "a greater sporting challenge".

"Naturally there's a chance of playing in the Champions' League. I hope Anderlecht and Dortmund will quickly come to an agreement," he added.

If Koller does decide to go to Dortmund, he will join his Czech Republic team-mate Tomas Rosicky.
