Sagna: Arsenal fans criticising Wenger just embarrassing
Wenger is still coming in for flak from supporters, with the Gunners sixth in the Premier League and struggling for consistency.
But French defender Sagna said: "We see that Wenger is a very, very good coach.
"When you hear the criticism it's a bit embarrassing, because we're at fault a bit. In, fact we are totally at fault.
"For Wenger's sake, we had to react. For him and for the club."
