There are few managers in Europe whose club's fans have taken to them as quickly as Liverpool fans have adopted Jurgen Klopp as one of their own.
The German has led the club to a cup final in his first season in charge, while producing plenty of memorable performances since replacing Brendan Rodgers in October.
And when we talk about memorable performances, we don't just mean the efforts of the team on the pitch.
Klopp's post-match interviews have also been the highlight of a season written off by fans when Brendan Rodgers was still in charge, and this effort after the league victory over Manchester City stands out.

We've seen plenty of tributes to that 'boom' moment, though we think we all know which was the best so far.

But the Anfield faithful have now taken it upon themselves to recognise that wonderful interview, by taking this flag all the way to Dortmund for Liverpool's match against his former club.

If you hear any noises of discontent at Signal Iduna Park, stop to consider whether the fans might be saying 'Boom' rather than 'Boo'...
