VIDEO: Jamie Carragher downs pint with Borussia Dortmund fans as he gets rowdy before PSG Champions League showdown

The ex-Reds star and CBS pundit interviewed a bunch of Dortmund supporters outside the Signal Iduna Park ahead of the club's Champions League semi-final first-leg clash against the newly crowned Ligue 1 champions. After the interview, Carragher clicked selfies with the fans and then chugged a pint of beer with them.

The Bundesliga side, who staged a remarkable comeback against Atletico Madrid to qualify for the last-four stage, took the lead at home against Kylian Mbappe and Co. courtesy of a strike from Niclas Fullkrug in the 36th minute. The last time the German club reached the semi-finals was during the 2012/13 season.

Luis Enrique's side will aim to turn things around in the second half and restore parity in the tie before they head home for the second leg.
