The Reds had one foot in the quarter-finals after beating Inter 2-0 at the San Siro in the opening leg.
But Jurgen Klopp’s side didn’t fare as well at Anfield.
After a goalless 60 minutes to start the game, the comeback seemed on when Lautero Martinez crashed home a fierce effort from outside the box.
But, just minutes after the goal, Inter were reduced to 10-men.
The Chilean forward got the ball but his follow through caught the Liverpool ace.
Sanchez, who was already on a yellow card, was subsequently given his marching orders. Watch the moment below…

Inter didn’t pose much threat in the remainder of the game. There were no further goals as Liverpool progressed to the quarter-finals.
Arsene Wenger did not agree that a red card should have been given to Sanchez.
Speaking on BeIN Sports, the Frenchman took aim at the referee for ‘killing the game at the wrong moment’.
He then accused Fabinho of ‘cheating’ to get Sanchez sent off. Wenger thought that Fabinho made the most of the challenge in an attempt to get his opponent sent off.

He added: “He was cheating. He made more of it. Maybe he had pain and he was touched. But maybe he could have got up quicker. When it’s one of your players, you say it’s clever. When you are completely neutral, you would say he could have made less of it.”
Wenger did also admit, though, that Sanchez could have been sent off in the first half for a challenge on Thiago.
Liverpool will find out their opponents for the last eight when the draw is made on March 18. Joining them in the hat are Bayern Munich, who thrashed Red Bull Salzburg 7-2 on Tuesday evening.
