Mac Allister wins it for Liverpool against Atletico on Barcola's eventful full debut

Alexis Mac Allister's superb strike saw Liverpool come from behind to beat Atletico Madrid 2-1 at Anfield as Bradley Barcola went off with "cramp" on an eventful home debut.Barcola was making his first start for Liverpool but felt his calf in the second half and the £123m signing was substituted having missed three good chances to mark the occasion with a goal. It did not impact the result thanks to Mac Allister's rocket. Marcos Llorente had opened the scoring for the Spanish side with his fifth goal against Liverpool when put through well by Julian Alvarez on the Argentine forward's return to the starting line-up. But that man Dominik Szoboszlai levelled it up before the break.

Jan Oblak saved to deny him in the build-up to Szoboszlai's goal, Ronald Araujo cleverly recycling the chance. And Mac Allister blasted in to spare his blushes for the second.

He has been used on the left by Paris Saint-Germain but showed his versatility playing from the right.

That pace looks like it will be a real weapon for Iraola.The worry was the sight of him trudging off before the hour. The Liverpool boss had stressed the need to manage Barcola given that he had not been involved in pre-season. Iraola needs him up to speed quickly. On this evidence, he can make a difference.What the result means and next fixtures...Liverpool fixturesChampions League fixtures
