Up until the 88th minute of the game between Anderlecht and Arsenal, Anderlecht was leading 1-0 and were on the verge of a shock result, but the Gunners fought back with two late goals to achieve an unlikely victory.
Kieran Gibbs scored in the 89th minute after a inch-perfect cross by Calum Chambers. Gibbs slotted the ball into the back of the net to save embarrassment.
But Arsenal created a shock of its own after Lukas Podolski scored a goal in injury time after some poor defending from Anderlecht.
The 3 points were the perfect birthday surprise for Wenger.
