Arsenal need a goal on Thursday night... but the Wanda Metropolitano is the last place you want to have to go looking for one of those.
Atletico keeper Jan Oblak has not conceded at home since January 20. He has stopped the last 20 shots he has faced in the new stadium. He made seven saves at the Emirates and he can do the same again in his team's new fortress.

Simeone was beaming after the first leg despite his near 90 minutes on the naughty step in the main stand. He knows 1-1 was a very good result to take home with him.
He trusts his players to build on that. Godin and company were heroic in the first 90 minutes and they have left the team at the doors of the Lyon final.

At 32, Godin has been a constant for Atletico Madrid ever since Simone took over seven years ago.
He was the rock around which Manuel Pellegrini built the Villarreal side that finished second in La Liga in the 2007-08 campaign. It was the highest finish in their
