Mathieu Flamini says Arsenal cannot afford to drop anymore points in their Premiership title battle with Manchester United.

"Now we cannot concede any more points," said the Frenchman. "We have to win all the time, especially when you are in the title race. We have to work harder, to concentrate more and I'm sure everything will be okay.

"I think it's not very good to think too much about the last game. Just try to learn from what happened before. We have to look forward, see what was wrong before and learn and keep going."
