Arsenal legend Martin Keown has heavily criticised goalkeeper Matt Turner for the way he allowed Sporting CP to score their first goal in the 2-2 draw in Lisbon.
The north Londoners took the lead through William Saliba after just 22 minutes, with the French international heading home a perfectly-weighted Fabio Vieira corner. However, Sporting went level just 12 minutes later, scoring a corner of their own through Goncalo Inacio.
But former Gunners centre-back Keown has far from impressed with Turner, who decided not to come and claim the cross before Inacio's finish. Speaking on BT Sport at half-time, Keown said: "Really he's killed everyone, because he's started to come and then doesn't.

"But [Jakub] Kiwior, too, he's got to do a little bit more than that. What I'll be saying though if I'm playing regularly with this keeper is: 'I'm going to have to go and head things. I can't really trust him.'
"There he has come and win it and be dominant and he didn't do it."
Sporting then took the lead early in the second-half through Paulinho before a freak own goal from Hidemasa Morita levelled the scoreline just seven minutes later.
