Enrique joined his former team in their celebrations as he continues his brave comeback from a brain tumour, which was removed in an operation.
Detailing his meeting with fellow full-back Robertson, Enrique told liverpoolfc.com: “I said to him after the game at the party, for me, he has been the best left-back in the world this year.
“Jordi Alba has been good as well but he has been unbelievable. He's given a lot of assists, contributed to the team offensively and defensively as well.
“He has been, for me, one of the best players for Liverpool this year."
