Atletico Madrid dethroned Liverpool on Wednesday night.
The Reds will not defend their Champions League crown after being knocked out of the competition by the Spanish giants.
Trailing 1-0 from the first leg at the Wanda Metropolitano, Liverpool levelled the tie through Georginio Wijnaldum in the first half at Anfield.
But despite controlling the game and numerous chances, they could not find a second goal and the tie went into extra-time.
Roberto Firmino did find a second goal soon after the extra period started, but Marcos Llorente stunned Anfield with two quick-fire goals, before former Chelsea striker Alvaro Morata rounded things off with a 120th minute third.
But while Morata made the headlines with his goal to secure the tie late on it was another former Chelsea man who was making headlines for the wrong reasons after the match.
Costa was well known for making enemies on the pitch while he played in the Premier League - a bad boy striker who would rough up defenders to get the upper hand.
But his bad boy ways came up off the pitch following the Anfield win.
With reporters waiting in the mixed zone after the match had finished to get interviews with the players, Costa strode out of the dressing room and walked past the amassed media and with a smile on his face started coughing as he went through.
Given the situation with the coronavirus it was an ill-advised joke, appearing to mock the outbreak that has killed more than 4,000 people worldwide.
Many Champions League games have been played behind closed doors as a result of the pandemic, with Serie A games in Italy postponed because of it and the threat of Premier League matches being played behind closed doors in the near future.
