Arsenal, Liverpool eyeing Bayer Leverkusen attacker Florian Wirtz

However, Bayer chief Fernando Carro insists the Germany international will only leave for big money.

"Never say never in the market," said Carro, "but one thing is certain: we will never let Florian go for less than 150 million euros."

This season, Wirtz has made 42 appearances, with 17 goals and 18 assists.
