Arsenal boss Unai Emery refused to criticise Sokratis Papastathopoulos after his red card contributed to the Gunners' collapse in their 3-1 UEFA Europa League defeat to Rennes on Thursday.
The north London outfit were leading courtesy of Alex Iwobi, but they shipped three goals after Sokratis was sent off in the first half at Roazhon Park for two bookings in the space of seven minutes.
Per Arsenal's official website, Emery was asked if Sokratis deserved to be sent off and said: "I cannot say to Sokratis because he has very good commitment, he has very good behaviour and he received two yellow cards in two actions of playing.
