Atletico Madrid coach Diego Simeone is wary facing Arsenal.
Simeone praised Arsene Wenger's coaching skills with Arsenal drawn against them in the Europa League semi final.
"With their history they are a very strong rival, they have a very important coach who is very capable with plenty of experience and quality footballers," said Simeone of Arsenal and Wenger.
"We will use the squad as always. With it being near the end of the season, the footballers have more desire and we will go out trying to give the best for the team and thinking in winning.
"This is the season where I am learning most about being a coach and improving."
