DORTMUND: Florian Wirtz and Granit Xhaka will both stay with freshly-minted Bundesliga champions Bayer Leverkusen beyond the summer, sporting director Simon Rolfes said Monday.

Leverkusen clinched the first league title in their 120-year history with a 5-0 thrashing of Werder Bremen on Sunday, with Wirtz scoring a hat-trick and Xhaka also getting a goal.
