Follow all the quarter-final second leg action live from Signal Iduna Park
Liverpool must pull off another famous European comeback at Anfield tonight if they are to knock out Real Madrid and reach the Uefa Champions League semi-finals. A 3-1 defeat to Zinedine Zidane’s Real in Spain means Liverpool have it all to do in the second leg of their quarter-final tie - though Mohamed Salah’s away goal will give the Reds hope of setting up a last-four battle with Chelsea.
