Borussia Dortmund boss Jurgen Klopp photobombs fan's picture with Marco Reus

Borussia Dortmund boss Jurgen Klopp has hijacked a photo taken by a fan posing with midfielder Marco Reus.

The 24-year-old Manchester United target stopped to take a picture with the supporter, but Klopp, who is known for his eccentric behaviour, decided to join in.

The snap was taken as the squad were boarding a train to their Bundesliga encounter against Eintracht Braunschweig on Friday, which ended 2-1 in Dortmund's favour.

The photo has since gone viral on social media.

On a score of 1 to Jurgen Klopp how cool is this photobomb? #klopp #bvb #photobomb pic.twitter.com/sDYWXXbV9x
