Mikel Arteta was overjoyed after Arsenal's huge win over big-six rival Liverpool.
The Gunners claimed a 2-1 victory at the Emirates to put them within two points of seventh-placed Spurs.
And Arteta was delighted that his players were able to gather momentum ahead of Saturday's FA Cup semi-final against Manchester City.
Speaking after the game, Arteta said: "In terms of energy and happiness in the dressing room, this is good medicine ahead of the semi-final.
"Against this team you have to take your chances, you need to defend, and you need a bit of luck, and we had all of that. We had belief. I was worried at 1-0 how we would react, but we were able to pick one moment and believe again.
"We were at it, and here is our reward. It is a massive job, you only need to look at the difference between the two teams today, the gap is enormous.
"But the gap in many areas, we can not improve it in two months. But the gap in accountability, the energy, the commitment and fight is now equal.
"And before it wasn't. I am very proud of that. With that, we can create something."
