Atletico found themselves dumped out of Europe's premier competition as Thomas Tuchel's side progressed to the last-eight with a 3-0 aggregate win. Suarez, who has been in red-hot form in LaLiga this season, scoring 18 goals in 24 games, has failed to find the back of the net in six outings in the Champions League this season.
Simeone chose to take off Suarez just before the hour mark, and spoke about his decision to do so in his post-match press conference. He said: "It’s normal that he got angry when he was taken off, players want to stay on. We wanted a new way to attack them so we made changes.
"I'm not looking for excuses. They deserved to win over the two legs. The first leg was even, but they got their goal. Today they were better than us and deserved to win. We tried to find a way to score, but we weren't at it up top despite our effort."
The Atletico boss was also asked if his priority is LaLiga, where his side sit just four points clear of second-placed Barcelona. "It's easy to have regrets after the tie is over," he added. "You can't have regrets, the game has gone now. We need to use it to learn.
"We wanted to stay in the Champions League, but we didn't play that well in this year's tournament, but I'm very happy especially with how João Félix played today. We looked to change our system, tried to press them, but they were able to get through it, they were just better than us. You can't say more than that. We need to improve."
