Wojciech Szczesny believes that defensive strength is the hallmark of the best teams - and Arsenal can show that at Chelsea.
The Poland goalkeeper contributed to a clean sheet at Tottenham last weekend to set the Gunners up nicely for another testing trip across London, where a win would close the gap at the top to just one point.
Arsenal are renowned for their attacking prowess but there has been a switch in narrative this season and Szczesny wants another clean sheet on Saturday.
I believe the defensive stability is what makes the big teams better than the other teams
"If you keep clean sheets you give yourself the best chance to win the game, just like you saw at Tottenham, when a very good strike even in the first minute can decide the game," he told Arsenal Player.
"I believe the defensive stability is what makes the big teams better than the other teams and that's what got us through this season so far, so we just want to continue that.
"I'd settle for the same kind of performance that we produced on Sunday against Tottenham when we weren't at our very best but we scored a very good goal and defended well for 90 minutes.
"That gave us the result so again if we turn up with a solid defensive performance that should hopefully be enough to give us the three points at Chelsea."Copyright 2015 The Arsenal Football Club plc.
