Daniel Carvajal has hinted that he will remain at Bayer Leverkusen next season.
The Spanish right-back joined the German club from Real Madrid on a five-year contract last July, but Los Blancos have the option to re-sign him this summer for €6.5m (£5.5m).
"Yes, absolutely," he told Bundesliga.com when asked if he enjoyed playing in the Bundesliga. "I like the way it's played, especially the Bayer Leverkusen tactical system and philosophy. Of course, I'm trying to improve every day to fit in even better.
"The games are more intense in Germany. The transition from defence to attack is far quicker. In Spain, you'll more often have a bit of a break in between.
"We have a very young squad and it's important that we keep developing in the right direction. If we do, I'm convinced that we will be successful again next season."
Bayer finished third in the Bundesliga this season with 65 points from 34 matches.
