Here are three quick thoughts from Arsenal's 3-0 Premier League win over West Ham on Wednesday at the Emirates. Everyone defended well together and we were very well structured.
Walcott said: "We haven't been defending well as a whole unit, not keeping clean sheets".
He said: "There were positive performances from everybody - from the goalkeeper to the strikers".
"It was a good result and a relief as well because we had gone through a bad period but the mentality of the team was healthy".
However West Ham have lost their last four matches and have been in free fall down the Premier League.
"We need to re-group quickly, have a couple of good days' training and then make sure we get those three points on Saturday".

Bilic admits West Ham are struggling for confidence right now and says he won't hide away from their struggles. Winston Reid, Angelo Ogbonna and Pedro Obiang also remain sidelined, with Obiang having undergone an ankle operation that will keep him out for the rest of the season.
Snodgrass replaced Antonio for the restart and, yet again, Collins was soon putting his body on the line to deny Ozil with a saving stop, while Nacho Monreal curled wide before Fonte and Masuaku clashed heads in another attempt to silence the Gunners.
The breakthrough finally came in the 58th minute when Ozil's shot from the edge of the box somehow found a way past Randolph and into the bottom-left corner. With the exception of last season, "Arsenal" with the "Hammers" no problems for a long time.
Last weekend, Thierry Henry believed that the reaction to Theo Walcott's equaliser against Manchester City was "weird", while Alexis Sanchez needed to encourage his teammates to celebrate Shkodran Mustafi's goal during the 2-2 draw. Aaron Ramsey and Oxlade Chamberlain may return for the Gunners.
