Bayer Leverkusen are not willing to be bullied in the transfer market this summer.

The German club are hoping to expand on their success this season.

Leverkusen secured a Champions League position thanks to their Bundesliga finish.

And the club's manager Peter Bosz believes they can hold onto key players such as Julian Brandt and Kai Havertz.

"Yes, it's a better chance [of Leverkusen keeping both players]," Leverkusen coach Bosz told Bayer 04 TV.

"I don't know. Kai will stay, for sure. And Julian, I hope he will stay. Every player wants to play at the highest level and we have the chance next season to play at the highest level.

"We're looking forward to it. Not only in the Champions League but also the Bundesliga.

"Our goal will be to be better than this season and therefore we have to work harder than this season and be more clear about how we want to play. It's a big achievement."
