“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,” he said.
“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.”
The Czech international believes the balance between youth and experience at Arsenal is such that it gives Arsene Wenger’s side a boost ahead of the new season.
“We have a good balance,” he said. “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. Everything depends on how well we do on the pitch. We have to compete with the strongest teams.
“There are a lot of talented players in our team, but the real strength lies in our numbers. This squad has a number of players ready to compete for every position, and we will need them all during the course of the season.”
