Arsenal manager Arsene Wenger says his team did well to bounce back from disappointing results against Liverpool and Leicester City at the start of the season.
The Gunners eased past Hull City on Saturday afternoon to register their third successive win in the Premier League.
And the Frenchman praised his players for producing a professional performance in the second half against the Tigers.
"I think overall we had a convincing performance in two different situations," Wenger explained.
"11 against 11, I thought we played well. When you play 11 against 10, it is, of course, not the same mentally and psychologically. But we remained serious and in the end we won the game in a convincing way, I would say overall.
"But we had a very difficult game against Southampton last week, then went away to Paris Saint-Germain. It's an away game, so you are happy with the three points.
"We had a big shock in our first game and I said straight away after that first game that we face a mental test to see how well we respond.
"We went away to Leicester and to Watford straightaway. So overall I think we responded well. We were not ready physically at the start of the season, we are now much better so let's hope we can continue our improvement."
