Tomas Rosicky admits Arsenal's style of game takes a lot out of the players.
"It is clear to see that we like to play together, which is visible in the celebrations as well," Rosicky told Sport. "And we all like to play the football we perform.
"On the other hand, I must say it is also pretty tough to play such a style of football. We are constantly moving and circulating.
"Following Henry's departure, players who were known for their big talent - like Adebayor, Van Persie - came out of his shadow as he was the No.1.
"The others now feel a big chance."
