Arsenal beat Sporting Lisbon 1-0 on aggregate in the quarter-finals, while Atletico Madrid defeated Spanish rivals Barcelona 3-2 on aggregate in the last eight.

Supercomputer predicts Atletico vs Arsenal
According to The Analyst, Opta's supercomputer has predicted the chances of each team’s victory in the first leg in Madrid, with Arsenal having the upper hand.
Diego Simeone’s side has a 33.6% chance of winning the first leg at home, while Mikel Arteta’s side is favoured at 36.9%, and the chance of a draw is 29.5%.
However, Arsenal has a tough task at hand if its status as the odds-on favourite is to be realised, as the hosts have won five home matches this season, losing only two.
The Gunners have been formidable on the road too, winning five matches and drawing one, making it a potentially closely contested match in Madrid.
What the managers said
Diego Simeone, speaking after his side’s 3-2 win over Athletic Bilbao in La Liga, claimed that his side reached the semi-finals through hard work and must do more against Arsenal.
“It’s been a struggle for Atlético to reach the Champions League semi-finals and finals. We’ve built this through hard work and with the support of our fans,” he said as quoted by Into the Calderon.
“We need them more than ever, and hopefully we can give them what they want on the field.”
Mikel Arteta was delighted with Arsenal’s win over Newcastle United at the weekend, which puts them back at the top of the Premier League table.

Arteta hopes to replicate the same success when they travel to Madrid, as they continue to fight on two fronts after elimination from the cups.
“I'm happy that we have a beautiful trip to Madrid to play the semi-final of the Champions League. It doesn't happen very often, so recover, and we're going to start to talk about Atletico now, and we'll go for it,” he said as quoted by Arsenal.com.
