Arsenal slipped to a 3-1 defeat to Rennes in the first leg of their UEFA Europa League last-16 tie on Thursday at the Roazhon Park.
Alex Iwobi gave the visitors the perfect start with the opening goal after just three minutes. The winger curled in a cross from the right that sneaked past goalkeeper Tomas Koubek at his far post.
However, there was drama at the end of the half as Sokratis Papastathopoulos was sent off after picking up a second yellow card, and Benjamin Bourigeaud fired in an equaliser for Rennes.
Rennes made the most of their man advantage and took the lead on 65 minutes through a Nacho Monreal own goal.
