Louis van Gaal revealed he gave up the touchline antics after a bizarre event in the 1995 Champions League final.
Manchester United manager Louis van Gaal says he used to be like Jurgen Klopp on the touchline until he developed the ability to control his emotions.
Klopp, who took over at Liverpool in October and comes up against Van Gaal's men at Anfield on Sunday in the Premier League, is renowned for being an entertaining figure in his technical area with his celebrations and antics.
The German is also known for getting in the ears of referees, something Van Gaal can relate to in his earlier days of management.
