Agent of Man Utd, Chelsea target Lewandowski upsetting Borussia Dortmund coach Klopp
Klopp barked: "With Robert, I have absolutely no problems. His advisers, however, are another matter. I don't want them near my players."
The trouble for Dortmund is that despite his best efforts, football chief Michael Zorc has failed to convince the Poland striker to open new contract talks. His current deal runs to 2014.
