Robertson was asked to nominate a line-up and concedes he'd go with Mane ahead of fellow striker Salah.
He explained, "Then I will go with the boy who plays in front of me, Sadio Mane. He brings a bit of pace, he brings the goals.
"I'll put him in ahead of Mo, just because I know it will annoy Mo Salah and that's perfect for me!
"But really, me and Sadio have a fantastic relationship. As long as I give him the ball, he's happy. As long as I do overlaps, he's happy, but I don't get much back.
"He actually calls me 'decoy' at Melwood - he doesn't even know what it means! Sadio is one of the best in the world."
