Diego Simeone refused to shake Jurgen Klopp's hand after seeing his Atletico Madrid fall to a 3-2 defeat to Liverpool in a dramatic Champions League contest.
The LaLiga champions saw Antoine Griezmann sent off, a penalty given against them and a penalty decision of their own overturned in a disappointing night for Simeone's side.
After the game, the Argentine boss sprinted straight down the tunnel refusing to shake the Liverpool manager's hand.
Klopp was seen holding out his hand and then gave a sarcastic thumbs up when Simeone ran down the tunnel, before the German went on to shake the hands of the Atletico players.
