Borussia Dortmund's Robert Lewandowski became the first player to score four goals in a Champions League semifinal on Wednesday as speculation mounted about his future.
.
The Poland striker opened his account in the first leg against Real Madrid in the eighth minute and added three more in a stellar second half to give his team a 4-1 advantage to take into Tuesday's return leg.
.
Lewandowski, who has scored in his last 12 league games, took his tally to 21 goals in 19 matches and sharpened the interest of major European clubs eager to sign him.
.
He has refused to sign a contract extension beyond 2014 but has kept quiet about his plans and Dortmund officials remain optimistic of keeping him.
.
"Robert has a contract until 2014 and there is no exit clause like with Mario Goetze," said club boss Hans- Joachim Watzke. "It is our explicit wish to keep him until 2014. That is why we are saying no to a transfer fee."
.
If Lewandowski decided to leave, Dortmund could collect a mutli-million transfer fee as he would move before the end of his contract. The club would be entitled to nothing if he left next year.
.
Dortmund have already lost one of their key players, Mario Goetze, with Bayern Munich paying 37 million euros for the gifted 20-year-old Germany international.
.
Speculation has been swirling around central defender Mats Hummels with media reports linking him to a move to Spain.
.
Lewandowski put Dortmund in the driving seat against Real when he latched on to a Goetze cross.
.
He then picked up a Marco Reus pass, turned and flicked the ball in to showcase the attacking qualities that have made him the Bundesliga's top scorer this season.
.
He drilled in his third in the 55th minute and added a fourth 11 minutes later with a cool spot-kick.
.
"This (performance) will definitely go down in history.
.
There are always the same films in the Borusseum. You will see Lewa's four goals there soon," said coach Juergen Klopp.
.
"It was an unusual game by my team and that third goal was worth every cent the broadcasters paid.
.
"I do not have the feeling that Robert is on the run and we are not the ones to send him away," he said.
.
"Let's wait and see what happens next."
This kind of sparkling is definately mind blowing. He proved to the world that its nt about money or big players, its abt teamwork
