It will take a monumental effort from Schalke to stop Leverkusen from here.
That's a tasty goal. Leverkusen play a bit of tippy-tappy football on the edge of the Schalke area before Adli pokes one into Wirtz who dances through and prods low into the net.
He has been having an excellent game, but Schalke's keeper has finally been beaten in this game.
Goalkeeper Efficiency of Ralf Fährmann
