Andoni Iraola takes charge of his first Champions League match as Liverpool begin their European campaign against Atlético Madrid - follow live with ESPN.

A day after revealing his disappointment over the lack of a new contract offer by Liverpool, Alexis Mac Allister delivered the perfect response with the winning goal in a 2-1 victory against Atletico Madrid in the Champions League on Wednesday.

Liverpool boss Andoni Iraola said it was difficult to ask for more from his Champions League coaching debut after the Reds came from behind to beat Atletico Madrid 2-1.

Liverpool got their UEFA Champions league campaign off to the perfect start as they came from behind to beat Atlético Madrid 2-1 -- with goals from Dominik Szboszlai and Alexis Mac Allister.

Iraola will be relieved that his team were able to shake off Marcos Llorente’s opening goal — remarkably, his fifth at Anfield — courtesy of Dominik Szoboszlai (after a lovely backheel by Ronald Araujo) and a thunderbolt from Alexis Mac Allister, whose future has been the subject of more debate this week.
