Correa has emerged as a major summer target for Klopp in the last 24 hours.
That was way back in September 2017 when the La Liga outfit travelled to Merseyside in the Champions League group stages.
Correa played the full 90 minutes and struck the equaliser for the visitors in the 72 minute.
Speaking after the match, Correa shared his admiration for Liverpool's quality while showing he knows a thing or two about the club's history.
“This is a really good point," he said.
"We had to overturn the form of the game to get it.
“Liverpool are full of quality, extremely fast and we had to get accustomed to that. My goal was just what we needed.
"Luis [Muriel] nearly had the winner in added time there and that would have been great.
“They say, here, that you never walk alone and our traveling fans ensured that was the case for us too."
