Liverpool striker Roberto Firmino wasn't surprised by Mohamed Salah's record hat-trick against Rangers.

Salah jumped from the bench to score a six minute treble as the Reds won their Champions League encounter 7-1 at Ibrox.

Firmino smiled: "It was amazing. When Salah scored the first goal, I said to Darwin that he was 100 per cent sure to score a hat-trick.

"I could feel it from the bench and he ended up doing exactly as I said, so I'm really happy for him."

Firmino himself delivered two goals and an assist before being substituted in the 73rd minute.
