Arsenal forward Danny Welbeck insists the club must keep on improving following an impressive start to their Europa League campaign.

Welbeck got on the scoresheet as the Gunners strolled to a 4-2 victory over Ukrainian side Vorskla Poltava.

"It was a convincing win," Welbeck told BT Sport. "It was difficult in the first half to impose our style of play but we had to be patient to try and implement things.

"We got a few goals but it was disappointing to concede a few too. With the squad that we have got, we are focused on the next game.

"Everybody looks forward to the next game and we always want to win. All the lads are enjoying it [under Unai Emery] and you can see the way he wants to play. We are right behind his ideas.

"We want to keep getting better and better. There are always standards and we want to keep on improving.

"It is healthy to have great players all over the pitch and to have everyone fighting to be in that starting XI. It is a good headache for the manager to have."
