Cape Town - Arsenal boss Arsene Wenger expressed his delight at seeing his team come from a goal down to beat Swansea 2-1 at the Emirates Stadium on Saturday.
The Gunners found themselves trailing for the third game in a row, when Sam Clucas drew first blood for the Swans midway through the first half.
But as they did against Everton in the league and Norwich in the EFL Cup, Wenger's side fought back to claim victory through second-half goals from Sead Kolasinac and Aaron Ramsey.
The north Londoners closed to within a point of third-placed Tottenham, and the Frenchman - who oversaw his 800th Premier League game at the helm - believes they will go from strength to strength.
"I'm very happy with the three points," he told Sky Sports. "I think overall we had a good domination, maybe in the first half our pace was not quick and sharp enough, but in the second we upped the tempo and created many chances.
"Again we showed mental strength to come back from 1-0 down to win 2-1. Overall it was vital for us to win the game today.
"The best always is to show on the pitch what you can do, and I am convinced we did that at Everton, against Everton, and again today. That can only make the team stronger as well."
Commenting on his milestone, Wenger added: "I don't know where all these games have gone because you always look forward and not back.
"And sometimes these numbers remind you you've gone a long way. You can only be grateful and happy because it's a privilege."
Arsenal next face the daunting task of travelling to the Etihad Stadium to face pace-setters Manchester City on a super Sunday of soccer action.
