Fernando Torres could make his return as Atletico Madrid bid to reach the Champions League quarter-finals on Wednesday.

Atletico are strong favourites to reach the last eight for a fourth straight year after Torres scored in a 4-2 first-leg win against Bayer Leverkusen in Germany three weeks ago.

Torres returned to full training on Monday for the first time since losing consciousness in a challenge with Deportivo la Coruna's Alex Bergantinos that saw the striker leave the ground in an ambulance.

However, the 32-year-old was released from hospital less than 24 hours later having suffered no serious injuries.

"We imagine that for Wednesday he will be available," said Atletico boss Diego Simeone.

Atletico have only lost one of 20 Champions League games at home under Simeone.

"We have a great result from the first leg, but we can't be complacent. We need to give our all again on Wednesday," said Atletico midfielder Koke.

Leverkusen travel to Spain under new management as Tayfun Korkut replaced the sacked Roger Schmidt after the first-leg defeat was followed up by a 6-2 thrashing at Borussia Dortmund.

However, Leverkusen are hoping for a comeback of Barcelona proportions after the Spanish champions fought back from a 4-0 first leg defeat to beat Paris Saint-Germain 6-1 last week.

"We know it's going to be difficult and it's hardly possible, but we will give it our all and try to make the impossible possible," said centre-back Omer Toprak.

Saturday's 1-1 draw with Werder Bremen left Leverkusen languishing in the bottom half of the Bundesliga.

Team news

Whether Torres starts for Atletico depends on Kevin Gameiro's fitness as he missed Saturday's 1-0 win at Granada with an abdominal injury.

Atletico will definitely be without captain Gabi and left-back Filipe Luis as they picked up yellow cards towards the end of the first leg.

Leverkusen will be depleted by injury and suspension themselves.

Benjamin Henrichs and influential midfielder Hakan Calhanoglu are banned, while Toprak, Jonathan Tah, Stefan Kiessling and captain Lars Bender are out injured.

Kai Havertz, 17, made his first start in the Champions League last month against Atletico but will not feature in the return leg due to school exams

Match stats

Atletico Madrid have only tasted defeat in one previous meeting against Bayer Leverkusen in European competition (W2 D2).

Atletico have progressed in both of their previous Champions League knockout ties when claiming victory the 1st leg (AC Milan in 2013/14 & Bayern Munich in 2015/16).

Bayer Leverkusen have reached the knockout stages for the fifth time in their last six Champions League campaigns. However, they haven't progressed past the round of 16 since 2001/02 when they were beaten finalists.

In fact, Bayer Leverkusen have lost nine of their last 10 Champions League knockout games (W1), their only win in that run coming against Atletico Madrid (1-0, February 2015).

Bayer Leverkusen have only been able to score five times across their last seven matches in Spain against Spanish opposition in the Champions League; never managing to record more than one goal in a single game during this run.

Antoine Griezmann has been directly involved in nine of Atlético's last 10 home Champions League goals (scored seven and two assists)

Charlie Nicholas' prediction

It was a fine result for Atletico in the first leg but they're still not playing that well, including Antoine Griezmann, for all his Manchester United admirers.

Yannick Carrasco has had to step up and deliver more goals this season, with Kevin Gameiro not being quite as prolific as they'd hoped.

However, they're already through in my opinion and they won't take any risks, which they're well suited to. They'll keep the ball, take the sting out of the game and wait for a chance to come to pick their visitors off.

Charlie predicts: 1-0 and Carrasco to score first - 30/1 with Sky Bet

Betting

Bayer Leverkusen are up against odds of 20/1 with Sky Bet to overturn the first-leg deficit and 17/4 just to win on the night, as Atletico are just 4/6 for another victory. Diego Simeone's men are currently 9/1 joint fourth favourites to win the Champions League, with their visitors the longest odds of those left in the competition at 500/1.

Antoine Griezmann heads the first goalscorer betting at 100/30 with Javier Hernandez considered Leverkusen's main threat at 15/2 to net first, while the strike duo are 11/2 to both find the net.
