Arsenal goalkeeper Wojciech Szczesny reckons solid defending from his team will go a long way in helping defeat Tottenham on Sunday.
Szczesny admits he has been concerned by the concession of goals in league games already this season.
And while the Gunners have an impressive home record against Tottenham, Szczesny is taking nothing for granted.
"Hopefully we can get a few more clean sheets in the Premier League because we have not kept one yet," the Poland international said.
"It is a little bit of an obsession for me, so hopefully we can improve on that. I don't like to concede - the one against Fulham does my head in.
"I am doing all right. We managed to keep a clean sheet twice out of the last three games. Hopefully we can still improve, but I am kind of satisfied.
"We just want to give the fans something to cheer about and make sure we get three points."
