Unai Emery isn't fazed with Arsenal's unbeaten run coming to an end on Sunday.

The Gunners remarkable 22 game streak without a loss was ended when Southampton beat them 3-2 at St. Mary's.

Emery's side have an opportunity to bounce back in the EFL Cup quarter-final against Tottenham Hotspur on Wednesday. And the Spaniard says his players are solely focused on the task at hand.

He said: "We can win, we can lose. We've won matches playing worse than we did on Sunday. Football is like that. We need to continue improving. Our analysis shows us it's the first time we've conceded three goals in this process.

"There's no excuses because we don't have a lot of centre backs. I think it's a little bit for all the players, all the positions on the pitch. It's also because they did their actions against us well. We need to improve by not conceding as many chances to the opposition. A clean sheet is very important in each match.

"Tomorrow is the next. A scoring moment is very important and we are second for that in the Premier League. But we need to do better in our balance defensively, and our hard work now is this."
