The 2-1 loss to the Baggies was a big blow to their potential title challenge this season.
The Gunners were beaten 2-1 on Saturday afternoon in a highly disappointing display from Arsene Wenger’s side.
The defeat was particularly disappointing as a win would have seen them go clear at the top of the Premier League table, with Manchester City losing heavily to Liverpool in the late kickoff.
The loss to the Baggies could prove to be a big blow to Arsenal’s potential title challenge, and Flamini has urged the side to recover quickly and focus on the next game.
“We tried and tried and tried until the last minute but we can’t give any excuses - today we lost the three points,” he told Arsenal.com.
“It’s a shame because we started the game well, we went 1-0 up and then after they scored [twice] before half time it became more difficult for us. Now it is important to recover and focus on the next game.”
The Frenchman has also absolved Santi Cazorla of any blame for his missed penalty in the game.
The Gunners were given the chance to level the scores late on, but the Spaniard slipped at the crucial moment and wasted the chance to secure a point for his side.
It was a disappointing moment that summed up an even more disappointing afternoon for his side, but Flamini has absolved his teammate of any blame, despite the criticism being aimed at him.
“The penalty, it can happen and Santi falling, there is nothing you can do,” he added. “We tried to push on in the second half, we had some opportunities but of course it is disappointing because we didn’t get any points.”
