Gabriel has praised Salah following Liverpool's start to the new season.
“Salah has shown his quality in the last two seasons, he has scored a lot," he told National Sport. “I don't train with him, but I know he is quality.
“I think its still early for me to say anything about this [City's title hopes being over], the season has only just begun.
“Of course, [Liverpool] are playing well, we know this, but we haven't played like we know we can. We can play like we did last season and win the title again."
