Sunderland boss Gus Poyet admits there's frustration over the manner of defeat at Arsenal.
Alexis Sanchez made the most of horrendous errors by defender Wes Brown and goalkeeper Vito Mannone either side of half-time to secure a 2-0 victory for the Gunners at the Stadium of Light.
Asked about the mood in the dressing room, Poyet said: "It's a little bit of anger, really, because when you know the team, the group was there and responded and they tried, they really fought hard for the result, and then two actions...
"Normally it takes you I don't know how many games to commit one of those mistakes, and we made two in the same game - and after last weekend - which is something that has put us in the position we are in, really.
