Wenger believes that Arsenal's participation in the Europa League has helped ease the injury burden on his squad.
“First of all, we rotated more in the Europa League and was able to rest more players," Wenger told Arsenal.com. “Afterwards, you always improve by learning from the seasons before, you learn more about the general concept of our training intensity.
“We also learn more about the individuals. We have a deeper analysis of what happened with the player last year, whether he got injured, how many games he played in three weeks and after he got injured. From the player's injury history, you learn when to rest him and when to play him."
Going into Saturday's game at Tottenham Wenger's side currently have the joint-fewest injury absentees of any side in the Premier League, with long-term absentee Santi Cazorla the only player guaranteed to be unavailable for the trip to Wembley.
