Borussia Dortmund coach Jurgen Klopp has hit out at the advisers of Robert Lewandowski.
A long-term target for Manchester United, Lewandowski has been linked with Tottenham Hotspur and Chelsea this week.
Klopp fumed: "With Robert, I have absolutely no problems. His advisers, however, are another matter. I don't want them near my players."
It is understood that the Poland striker has yet to open new contract talks with Dortmund and his current deal runs out in 2014.
