Salah, 33, was left in Liverpool as his teammate travelled to Milan following his explosive interview, in which he claimed he had been ‘thrown under the bus.’
Liverpool went on to beat Inter Milan 1-0 at the San Siro thanks to a controversial late penalty from in-form midfielder Dominik Szoboszlai.
After the game, left-back Robertson, 31, weighed in on Salah’s situation at the club, calling the forward “one of the greatest players to play for this club.”
He said: "A tough situation. We're talking about one of the greatest players to play for this club. I signed in the same window as him. Whatever has happened, happened. Internally, we're all together.
On Salah's future:"That'll be up to other people, it's not up to me. I love playing with Mo Salah and I hope to continue playing with him.
"We know how important being in that top eight is and avoiding a play-off. We got unlucky last season with who we drew."
