Arsenal goalkeeper Petr Cech says he was impressed by his new team-mates after making his debut in the 3-1 win over Everton in the Barclays Asia Trophy final on Saturday.
The 33-year-old joined the Gunners after deciding to end his 11-year stay at Chelsea and will be Arsene Wenger's regular goalkeeper in the upcoming campaign.
He believes Arsenal have the necessary experience to challenge Chelsea and the two Manchester clubs for the Premier League title.
"What I've found is a group of players who work very hard and are focused on what they are doing on the pitch to get ready," Cech told The Telegraph.
"I've found the team spirit quite extraordinary.
"Everybody pulls in the same direction, which is why I believe we will have a successful season. If you have a game with two big teams it's decided by the little details.
"In all those games Chelsea were on top we managed the little details better. I hope to be on the winning side again. It's as simple as that. I play football to win games.
"We have a good balance.
"We have players with a lot of experience, who have won the World Cup for example, and young players who want to prove their point and play as much as possible.
"We have experienced players and hungry players so that balance gives us an advantage."
