Although Klopp admits Hazard is a "special" talent, the Liverpool manager is focussing on far more than Chelsea's star man, with Jorginho among those who will also be key.
Eden Hazard's brilliant victor knocked Liverpool out of the Carabao Cup in midweek (Martin Rickett/PA).
Ever since Hazard signed along the dotted line in the summer of 2012, we have been desperate for him to establish himself among the best in the world.
"But I think I tried to do my job the best I could, and I can't be too disappointed (with) the way I played".
Zola is convinced the Belgium playmaker, who hinted at a desire to join Real Madrid after the World Cup in a move which did not materialise, can get better and better. Because I think that we have seen only 70-80 per cent of his potential, so if he can improve he can be the best in the world. And so I want him to be the best in the world.
But Sarri insists Hazard isn't there yet because he can still add another layer to his game by training with even more desire and drive.
When then asked about Messi and Ronaldo, Barkley added: "They are probably a lot more selfish than Eden is".
"We need to see the last training before we decide, but they are nearly ready so the situation is better than three or four days ago". I'm feeling good since the FA Cup final.
"Eden is growing fast in his maturity and the choices he makes on the pitch, and in my opinion we haven't seen the best of him yet".
Maurizio Sarri has enjoyed an excellent start to life in England and while their winning Premier League run came to an end with a 0-0 draw at West Ham last weekend, the west Londoners could go back to the top of the table with a win tomorrow.
Hazard has played seven matches for the Blues this season so far, scoring six goals and assisting a further two strikes.
"It is very hard to compare him with other players".
The Belgium global is also 8/5 for Hazard to find the net once again this weekend.
Klopp gave Fabinho his first start and put together a back five consisting of former first team members; Dejan Lovren, Joel Matip, Alberto Moreno, Nathaniel Clyne & Simon Mignolet.
