"Sadio Mane, world class, but not every day. Roberto Firmino, world class, pretty much every day."The 26-year-old forward has only missed one Premier League game this season and it's no wonder Henry claimed he would've loved to play alongside him.

Asked who stood out in Liverpool's 2-0 win at St. Mary's, the retired Arsenal and Barcelona star responded: “Firmino, not for the first time.

“The way he plays, the way he works.

"The assist that he had, just everything that he does. That’s why he always plays."

Henry brilliantly dissected Firmino's back-heel assist for Salah - he spotted something brilliant that the Brazilian did that very few had.

“I would have liked to have played with this guy,” Henry added.

That's about the highest praise you can receive.
