RB Leipzig CEO Oliver Mintzlaff has warned Timo Werner that he will be sold if he fails to sign a new contract in the summer.

Werner, who has scored 11 goals in 17 league appearances this season, will enter the final year of his contract next season.

Liverpool and Bayern Munich are reportedly interested in the German's services and they will have an opportunity to sign him should negotiations continue to stall.

"Of course we have to know at the latest after the end of the season," Mintzlaff told German publication Kicker . "A club like us cannot afford to go with Timo Werner in a final contract year.

"It's logical that such a player should be courted by clubs that have a very different sporting perspective and different financial possibilities than we have.

"But as long as we develop as a club, and of course the Champions League participation would be very helpful, I believe that Werner is still in good hands with us.

"If Timo does not strive for the highest possible salary, then it would be a good investment in his sporting future."
