Arsenal boss Mikel Arteta has defended his back four.
Arteta insists Arsenal have tightened up at the back — despite not keeping a clean sheet since January.
He said: “If you look at the clean sheets we had at the time of those games against Liverpool and Manchester City, to compare to what we have done now, we have to relate as well the amount of chances and shots we allow on our goal.
“Now we concede much less than before.
“But we make some big errors that have cost us a lot of goals in recent weeks.
“It's true, it's always difficult to find that balance because we are producing much more football.
“Overall, we are doing much better than we used to do, but at the end the results define the perception because we are here to win.
“I cannot just judge it by saying, 'Here, we were more stable to now'. There are many things to look at.
“If you look at what happened against Slavia Prague on Thursday, if we won 3-1 it would have been perfect.
“But we didn't, we conceded a goal in the 93rd minute from a set-piece and we missed some big, big chances, so now the perception is different."
