Manchester United fans have been left incensed by Jurgen Klopp's touchline antics during Liverpool's thrilling 3-3 draw with Arsenal.

The German was being his usual visibly excited self on the sidelines and at one point launched a water bottle.

Liverpool went two goals up through Philippe Coutinho and Mohamed Salah. But an Alexis Sanchez diving header inspired an Arsenal comeback. Granit Xhaka and Mesut Ozil then scored to put the hosts 3-2 up.

But there was one last twist to the tale when Roberto Firmino equalised in the 71st minute - which was when Klopp threw a water bottle.

After witnessing that the German received only a warning following his antics, Man United fans erupted on Twitter.

Jose Mourinho was not only sent to the stands for kicking a bottle in frustration during Manchester United's 1-1 draw with West Ham last season, he also received a one-game touchline ban.

The Football Association ruled that Mourinho had "aggressively kicked the bottle in a manner that could have endangered people around him regardless of the motivation to do so".

Mourinho was also fined £16,000.
