Liverpool will travel to Barcelona to play the Champions League semi-final match against formerAnfield favourites Luis Suarez and Philippe Coutinho.
The Reds progressed by securing a 6-1 aggregate victory over FC Porto with a 4-1 win in Wednesday's last-eight second leg at Estadio do Dragao.
Former Liverpool players Suarez and Coutinho have not played against Jurgen Klopp’s side in a competitive match since their moves from Anfield.
And now it’s time when they will play against Liverpool and Klopp has a message to the former Liverpool players.
"Honestly, the only thing I am thinking about is Cardiff on Sunday," the Reds boss said.
"For these two boys, it is very special, because they are Liverpool legends.
"But I don't think it will be a friendly game, we have to fight and work and they will do that as well.
"It is a wonderful game, Liverpool vs Barcelona in the semi-finals. Now let's try to do the best there and we will see what happens."
Barcelona, who reached the semi-finals by defeating Manchester United, will host the first leg of the tie on Tuesday April 30/Wednesday May 1, with the second leg to take place at Anfield on Tuesday May 7/Wednesday May 8.
