Liverpool beat Burnley 3-0 with Mane and Roberto Firmino already on the scoresheet, but Salah failed to find the net.
Salah passed up the chance to tee Mane up for his second late in the game, opting to shoot, and his teammate was fuming with that decision when he substituted just minutes later.
Henderson was one of several Liverpool players sitting on the bench left baffled by Mane’s angry reaction to being taken off, but insisted the issue was now sorted.
‘I couldn’t really understand at first, but then when he came in, he was laughing and joking,’ said Henderson.
‘The most important thing was we got the result, Sadio knows that.
‘He performed really well again. Him and Bobby were really big second ball. He had a fantastic game.
‘Like I said, we want to push each other. We want to improve all the time. I quite like that now and again. I think we need it.’
Mane’s rage was quickly dampened by Milner and Firmino, who both had a chat with the Senegal international.
