Thomas Tuchel is demanding his Mainz side end a run of four consecutive draws with more incision against Bayer Leverkusen tomorrow.

Rather than gaining points in those games, it has more often been a case of dropping two, which is why Tuchel now wants to see his side fully rewarded for their efforts.

``We need to be more effective,'' he said. ``We need to be more ruthless than we have been in our recent games.''

Tuchel insists his side's form is not a concern, though, and they remain just two points adrift of the top six and a place in Europe for next season.

``The four draws have not put us under any particular pressure,'' Tuchel told reporters.

``It's not the case that we are lacking any fundamentals. It is more the case that we are putting a lot into the games but not getting enough out of them.

``That can only lead us to wanting to turn things around against Leverkusen, but that's going to be tough.''

Indeed, Mainz come up against the third-strongest side in Germany, considering the current league table, and they are keen to maintain that position to secure Champions League football.

And they have been given a boost with the news that captain Simon Rolfes has extended his contract by two years.

``I'm delighted by that,'' said joint-coach Sami Hyypia. ``He is our captain and a very good and important player, also in the dressing room.

``Simon always has a positive influence on things.''

Rolfes is set to make his 224th appearance for the club tomorrow, and many more are now set to follow.

``I have had a wonderful and successful time with Bayer and we want to develop step by step,'' the 31-year-old told his club's official website.

``We have the right blend of experienced and young, talented players and I want to make my contribution to us being successful in the future.''
