Unai Emery is delighted with Arsenal's improvement.

The Gunners have won four straight after losses to Manchester City and Chelsea in their opening two games.

"The players have shown since the first day of pre-season they are trying every day to do the best," said Emery.

"I think we are improving every day and I am very happy.

"But we need also time, we need to continue working, improving. Winning is better I think to find this but I think we are on the way."
