Swansea City goalkeeper Michel Vorm admits they were found wanting against Arsenal.
Vorm has called on his team-mates to improve their concentration after conceding twice in the space of four second-half minutes on Saturday.
Vorm said: "If you're not 100 per cent focused Arsenal can kill you. After the first goal we were a bit all over the place, and with the quality players they have, they take one or two touches and they're in.
"That's something we will have to work on."
