Borussia Dortmund coach Jurgen Klopp has warned Manchester United that Robert Lewandowski will not be sold during the January transfer window.
United have been linked with the 24-year-old Poland international for some time and were believed to be considering a move for him in January.
However, Klopp has made it clear the player remains under contract with the German champions and has shown no interest that he wants to leave just yet.
"I'm not afraid he will leave. Manchester United are one of many teams showing interest in him. But the fact remains the contract is with us," Klopp reported.
"The time when big, rich English clubs tried to take our players from Germany, thank God, is over. In the second half of the season he'll be with us."
Borussia Dortmund stand in the way of Manchester City qualifying for the Europa League with the Premier League champions needing a victory to have any hope of progressing to the second tier competition.
Although Dortmund are already through to the knockout stages of the Champions League, Klopp expects his side to play for the win.
"This is a Champions League game. When a team is through there is sometimes a temptation to rest players but that is not for us. We are going to play with a good team. It will be a high-tempo game and we have got to try to put a fresh team on the pitch, but obviously there will be changes," he confirmed.
"The match at City [on matchday 2] was surely one of the best ever for a Borussia Dortmund team. We were extremely quick, ran extremely well and were tactically very strong.
"Normally you win such a game, but that was not the case then. As it turned out, it didn't do us much harm. I can't really say how [Tuesday's] game will develop because I have no idea how the [City] team will line up."
