The match ended 2-2 and leaves the German side in the driving seat to win the group, while Arsenal still look reasonably comfortable to make it to the last 16.

"For us it was important first of all not to lose and if possible to win," Wenger said. "We managed the first part, not the second one.

"I felt that overall we played reasonably well, but we dropped physically in the second half and the regret we have is that overall we conceded the goal just before half-time and we missed a chance at the end of the game. I think the two, of course, have a big impact on the result overall. Schalke never gave up and worked hard."
