Atletico Madrid coach Diego Simeone is wary facing RB Leipzig.
Atletico will meet RB Leipzig on Thursday night in the Champions League quarterfinal.
"It's a big match against a fantastic team and coach," Simeone said in his pre-match press conference.
"They change positions constantly and they attack a lot.
"Their numbers show what they're capable of, so we have a lot of respect for them."
"I don't think the win over Liverpool can be a reference point because the enthusiasm faded over time," he said.
"That win was a long time ago."
