RB Leipzig look to maintain Rangers focus as chief hits out at Christopher Nkunku transfer talk

RB Leipzig chief Oliver Mintzlaff has been forced to take a stand against transfer interest in star man Christopher Nkunku ahead of the clash with Rangers.

The French talisman was the key man again for Leipzig as they saw off Union Berlin, winning a penalty that helped rescue the German Cup semi-final.

Nkunku has been linked with a host of clubs including Manchester United, Bayern Munich and Liverpool after scoring 17 goals and chipping in with another 16 assists so far this season.

With the Europa League semi-final clash with Gio van Bronckhorst 's men, Mintzlaff has warned potential suitors about a deal to keep the player focussed on his football.

The Red Bull brand global head of football, said: "I've said it many times and I want to say it again, Nkunku will be our player again next season.

"I accept in football, nobody is basically unsaleable, but we won't be letting him go.

"He was one of our best players in the first half of the season, even if it didn't go so well.

"But now, under Domenico Tedesco, he has ignited the next stage of development and he will continue doing that next season too."
