Arsenal captain Robin van Persie has hailed his side's win over Chelsea as a huge result after his hat-trick helped to keep them in the hunt for the Champions League qualification places.
The Gunners trailed at half time until goals from Walcott, Santos and a Van Persie brace saw them run out 5-3 winners at Stamford Bridge.
After the game, Van Persie told Sky Sports: "You can see how happy we are at the end because we fought hard for this game. Every single one of us showed character and it’s a big, big win for us today."
The Dutchman put the Gunners ahead after a John Terry slip left him one-on-one with Petr Cech and he admitted he was surprised that the England defender had made such a crucial mistake.
He continued: "I was quite surprised because it was just an easy backpass, I only saw it late in the action that he actually slipped because I was closing him down.
"I suddenly realised in a couple of hundredths of a second that I was one-on-one with Cech and a couple of things came to mind but I did the easiest part and just passed him to slide it in."
The 28-year-old went on to suggest the clash was a great advert for the Premier League and admitted his delight that his hat-trick had come at such a tough ground to visit.
"I think we showed absolutely everything that the great game can give to the world," he continued.
"Eight goals in total, Chelsea played well and created a lot of chances as well. We did really well, in the end we got two more goals so we’ve got a lot to offer.
"[The hat-trick] means a lot because in my opinion this is one of the hardest places to come to."
Van Persie's team-mate Aaron Ramsey was at the heart of an impressive creative performance from the Gunners' midfield and he praised the match as entertaining for fans and players alike.
"It was a really good game for us to play in," the Wales captain said.
"We showed great character coming back from being behind so I think it was a great game for us and the fans as well.
"I think we deserved to win in the end, we created a lot of opportunities and took a lot of them."
The 20-year-old admitted his side were disappointed to go in at half-time behind but said they showed great spirit to get back into the match.
He said: "I thought we created a lot of opportunities in the first half and we missed two early on.
"I think it was a bit of a blow and you could see from the reaction in the changing room that we were very disappointed going in a goal behind.
"We showed great character today, played some wonderful football at times and we did very well in the end to get the win.
"Every goal was important and [Walcott's equaliser] was no different but as I said it was great character from the team.
"I think we’re finally gelling together now and we’re finally showing what we’re capable of doing and this is just an example of that."
The Welshman conceded that the Gunners' defending may need improvement but insisted the three points were all that mattered.
"It was important just to come here today and get the three points," he continued.
"I’m sure the manager will look over some of the defending as a team and we’ll work on that but I think the most important thing is that we got the three points here today and we’re delighted with that."
