Diego Simeone compared Jan Oblak to Barcelona superstar Lionel Messi after the goalkeeper's exploits as Atletico Madrid eliminated Champions League holders Liverpool.
Oblak produced a man-of-the-match display with a number of important saves in Atletico's stunning 3-2 extra-time victory over Liverpool at Anfield on Wednesday.
Liverpool were on top for much of the last-16 second leg but they could not move clear of Atletico or get the better of Oblak as the visitors secured a 4-2 aggregate triumph thanks to Marcos Llorente's brace and Alvaro Morata's late goal.
Regarded as one of the world's best goalkeepers, Oblak earned high praise from Atletico head coach Simeone post-match.
"We have a goalkeeper who is the best in the world, no doubt," Simeone said. "I have been saying that for some time.
"It's like Barcelona who have Messi. He decides games with his attacking play; Oblak resolves them with his saves."
Llorente came off the bench to replace a frustrated Diego Costa and Simeone added: "Llorente revolutionised the team.
"I'm very happy for the team and the club. It was a historic match against an extraordinary opponent with great intensity and a beautiful stadium.
"They pushed and held, without us ever moving away from our plan and with everyone's effort we succeeded.
"It gives me an enormous joy because, although it seems simple, it's not simple to win."
