It took a late Thomas Lemar goal to secure the three points and there was frustration as the clock ticked on, with Morata evidently unhappy when referee Javier Alberola Rojas tapped him on the back as he had a word with the player.
After the match, Simeone was asked about the incident and said: "He was angry about what happened.
"It reminds me of the time I did that to an official and got a four-game ban."
It was a late goal from that won the game for Los Rojiblancos and Simeone said he always believed it would be a game decided by fine margins.
"Whoever had a chance and took it was always going to take the points," he said.
"They didn't let us do the damage we wanted.
"But thankfully it was us who scored."
Por esto Morata se ha quejado de que le ha dado una colleja durante 10 minutos y hasta ha ido a por el al final del partido. Cuántos veranos le faltan a este chico..— Reylear CanalApuesta (@reylear1) April 20, 2019
