Arsene Wenger says Atletico Madrid’s biggest strength is that they have ‘no weakness’.

The Gunners take on the La Liga giants tonight in the first-leg of their Europa Leg semi-final.

Atletico are favourites to win the competition having only conceded 18 times all season in Spain, and Wenger says he is well aware of how bigger taking on Diego Simeone’s side will be.

“The rules in Europe make the weight of an away goal very strong,” said Wenger, “That’s why when you play the first game at home, you’re a little bit in a difficult psychological situation because you know that you have to score but as well that every goal you concede can be a huge handicap.

“I would say one of their strengths is that they have no obvious weakness. they are a very efficient team and a team who can use every weak moment of their opponent. Overall I must say that is their main strength.”

The Frenchman is set to step down at the end of the season from Arsenal, but is yet to win a European trophy in his 22-year-spell with the club.
 
And Wenger says winning the Europa League would be the perfect send off.
 
He said: “I want to do it for [the players], to achieve something with them because I feel they have a special mental quality. My biggest satisfaction would be to be successful together with the group of players that I have.
 
“I’ve seen them behave the whole season and they deserve it.”
