The German boss was asked to elaborate on his comments about the ref following the game against the Hammers.

Pressure seems to be piling up on Jürgen Klopp's men, and the boss' recent words against referee Kevin Friend are testament of a potential crisis at Liverpool.

The game between Liverpool and West Ham ended in a draw, but Klopp's post-match comments regarding the ref's performance caught the eye of the English Football Association.

Klopp stated that Friend had changed his stance after the first 45 minutes, since he "realized" that Liverpool's goal should have been disallowed due to an offside position. Once the game restarted, Klopp believes that Friend's calls were biased and eventually had an effect on the outcome of the game.

The German boss tried to talk to the ref after the game concluded, but his efforts were useless due to the officer's reluctance to talk to the tactician.

This is how the exchange between Klopp and Friend took place, according to a report by The Sun.

"Klopp was complaining about Kevin and accused him of inconsistencies in the second half. Kevin told him he had to go away and they can't talk on the pitch. Klopp then asked 'I can't talk to you?' and Friend repeated 'Not now and not here'. Then Klopp called him 'arrogant' and walked off," a source told The Sun.

The ref's comments are being investigated by football's governing body in England. Although a ban seems unlikely, Klopp's comments might force the FA to slap a ban on him. Let's wait and see how this issue develops in the next couple of days.
