Robert Lewandowski has declared that its crucial Bayern Munich keep hold of Thomas Muller.
Muller saw a massive offer from Manchester United turned down by Bayern last month.
Lewandowski credits his rich scoring form to the presence of Muller.
“It helps me a lot that Thomas Müller plays close to me as a second striker.
“It’s hard to keep the ball, if you are up against four defenders and two defensive midfielders on your own.”
