Arsenal midfielder Alex Iwobi says they cannot dwell on defeat to Southampton.

Iwobi admits they let themselves down for the 3-2 loss.

He said, "I guess we weren't concentrating throughout the 90 minutes. We had spells where we weren't defending well as a group. It's something we have to dust ourselves down from and keep on going. We can't let our heads drop from this defeat, we just have to push on to the next match.

"Of course, they deserve some credit. They had a gameplan and they stuck to it and did well against us. But it's disappointing from us and we have to keep going again.

"We had a lot of chances to win this game, I believe. But we have to give ourselves a bit of credit that we were able to go on this unbeaten run and now we have to start over again.

"We have to react well, we have to keep on going. It's a bit unfortunate that there were a couple of injuries but we have to keep on going and keep on fighting throughout the season."
