Liverpool 2-1 Leicester City
Coutinho scored the goal of the tournament to seal the victory with one minute of the first half to play, curling a stunning strike past Kasper Schmeichel and showing why he is a rumoured target for Barcelona.
Christian Fuchs crossed a dangerous ball into the box after a fine pass from Marc Albrighton down the channel and the Algerian striker rose above James Milner to head into the net.
Eight minutes later, Liverpool were back in the game with a brilliantly worked goal. Salah slid the ball across the top of the box to Coutinho, who chipped the ball expertly over the top to the Egyptian winger as he made his way into the box and nodded past Schmeichel.
But the best goal was saved for last as Coutinho produced a spectacular effort in the 44th minute. Salah was once again involved as he linked up with Firmino, before the latter tapped the ball into the feet of his fellow Brazilian. Coutinho then let fly with the sweetest of strikes that curled past Schmeichel into the bottom corner to give the Reds a half-time lead.
