With the score tied a 1-1 on 54 minutes, Hart made a point-blank save from Moussa Diaby with his feet, only for the ball to land in the path of Amine Adli with the goal gaping.
However, Hart rushed back to his goal and plunged in front of the young Frenchman near the goal-line, stopping the ball from going over the line and then managing to control it with his hand as the loose ball squirmed away from him.
Minutes later, Celtic went on to score via Jota to go 2-1 ahead, although Leverkusen went on to win the match 3-2 and end Celtic’s hopes of reaching the Europa League knock-out stage.
The save brought a lot of praise for the England international, with former Celtic and Scotland goalkeeper Rab Douglas tweeting: “Joe Hart take a bow. Outstanding.”
Former England winger Trevor Sinclair also hailed Hart, tweeting: “Joe Hart with an 80/20 challenge against him & with his hands and won it to keep the ball out the net.”
