We're underway at the Wanda Metropolitano.
Good evening and welcome to the Champions League round-of-16 first leg clash between Atletico Madrid and Liverpool at the Wanda Metropolitano.
Atletico enter the contest looking to take the scalp of the holders to reach the quarter-finals for the first time in two seasons. Diego Simeone's men have not been in great form of late, winning only one of their last seven matches in all competitions. They allowed Valencia to come from behind twice to earn a 2-2 draw in their last outing at the Mestalla at the weekend. Los Rojiblancos did finish second in the group stage behind Juventus and will know that they will need to elevate the standard of their play to overcome Jurgen Klopp's side.
Liverpool's march towards the Premier League crown took another step forward with their win over Norwich at the weekend. They're now 25 points clear of Manchester City in second place, leaving them within touching distance of the title. The holders did get off to a poor start in their Champions League campaign, losing 2-0 to Napoli on the road. The Reds were strong enough to bounce back, but there is reason to fear Atletico and Simeone in a knockout fixture in their bid to qualify for the quarter-finals.
ATLETICO MADRID (4-4-2): Jan Oblak; Sime Vrsaljko, Felipe, Stefan Savic, Renan Lodi; Saul Niguez, Koke, Thomas Partey, Thomas Lemar; Alvaro Morata, Angel Correa.
ATLETICO MADRID SUBS: Antonio Adan, Jose Gimenez, Marcos Llorente, Diego Costa, Vitolo, Yannick Carrasco, Mario Hermoso.
LIVERPOOL (4-3-3): Alisson; Trent Alexander-Arnold, Joe Gomez, Virgil van Dijk, Andrew Robertson; Fabinho, Jordan Henderson, Georginio Wijnaldum; Mohamed Salah, Roberto Firmino, Sadio Mane.
LIVERPOOL SUBS: James Milner, Naby Keita, Adrian, Alex Oxlade-Chamberlain, Takumi Minamino, Divock Origi, Joel Matip.
The first half has gone perfectly to plan for Simeone and his team. They have the lead and are now able to sit back to absorb the pressure from the Reds, with the possibility of hitting them on the break. It should be another tense battle in the second half.
Thanks for joining our commentary this evening. Until next time, goodbye.
Atletico are next in action at home against Villarreal on Sunday in LaLiga, while Liverpool have almost a week off as they host West Ham United in the Premier League next Monday.
