WATCH: Irish fans in Austria serenade the world's best Jürgen Klopp lookalike on the train

Kloppelgänger.

All Irish fans must have been singing after the 1-0 win in Austria, but if you happen to also support Liverpool, there's a good chance that you might be merrier than most.

Jürgen Klopp's prolific side have made a blistering start to the Premier League season and they're the team to catch at the top of the table. The same can also be said for Ireland though because Martin O'Neill's men are currently top of Group D after picking up 10 points from their first four qualifiers.

The Irish fans were in fine voice after James McClean's winner secured all three points yesterday, but if they ever needed an extra reason to sing, this Jürgen Klopp lookalike on the train in Vienna definitely provided one.

This summer in France provided us with plenty of evidence about how talented our supporters are when it comes to belting out a few tunes - nuns, babies and the general French public can testify to this - but it's very rare that they've performed a private gig for such an illustrious "football manager".

This gentleman is the spitting image of the Liverpool manager, he even has his trademark smile!
