Arsenal lacked physical intensity - Arsene Wenger

Arsene Wenger says his side played "reasonably well" but that his team's "physical intensity dropped off" after watching Arsenal surrender a two-goal advantage in Gelsenkirchen to draw 2-2 against Schalke 04.

Theo Walcott's eighth goal in 13 games and Olivier Giroud's strike had given Arsenal a 2-0 lead, but Klaas-Jan Huntelaar scored just before half-time to reduce the deficit and Jefferson Farfan equalised after the break with a deflected effort.

Schalke's comeback was the second time Arsenal have relinquished a two-goal lead in the Champions League, the first being against Bayern Munich in December 2000.

Arsenal lie second in Group B following the result, one point behind Schalke.
