Kolo Toure is anticipating an 'unbelievable' atmosphere when Arsenal visit Villarreal on Tuesday evening.
The Gunners will be looking to claim a good result at El Madrigal in the first leg of their UEFA Champions League quarter-final but Toure knows what to expect from the last time the sides met.
Arsenal escaped with a goalless draw in Spain after Jens Lehmann's late penalty save, meaning they progressed to the final having already beaten Villarreal 1-0 at home.
Toure is confident Arsenal will come out on top again over two legs, although he realises Villarreal will provide a stern test.
"When we played them in 2006 they made us work hard," Toure told Arsenal TV Online.
"I was happy to score a goal in that first match but the second game was really difficult and in the end we were lucky that Jens saved the penalty.
"This time it is going to be really tight again. We have to concentrate and not think it is going to be easy.
"The atmosphere there is unbelievable, you can feel the pressure from the fans because they are so close.
"However, we are used to that in the Premier League, which is going to help us a lot."
Arsenal have been in fine form of late and a number of their top players are beginning to return from injury, with Cesc Fabregas and Emmanuel Adebayor both impressing against Manchester City on Saturday after spells on the sidelines.
Toure believes the Gunners can enjoy a strong finish to the season, but only if they approach each game with the right mindset.
"At the moment our squad is really strong and we still have some players to come back," said Toure.
"It is great to have Cesc playing again and he is going to help us to keep winning games.
"This month is really important and we have to stay focused because each game is going to be crucial."
