Review ShowIpswich 0-2 Liverpool: Analysis of influential Gravenberch and record-breaker Salah
During his regular post-match Review Show, which is now available to watch on LFCTV GO, Mellor analysed an impressive second-half display by the Reds, and in particular Gravenberch, in Saturday's Premier League opener.
"Ultimately it was about getting the three points, which we did, keeping a clean sheet and that quality came through in the end for Liverpool in the second half," said Mellor.
"Gravenberch was magnificent, he earned the right to start and he delivered.
"He had 71 touches in the game and 59 passes. We know he can dribble with the ball, but he was always an option for his teammates, I thought he was magnificent."
Mellor also highlighted the performance of Mohamed Salah, who netted on the opening day of the season yet again to set a new Premier League record.
The Egyptian hit his ninth goal in the first fixture of a campaign to move ahead of Alan Shearer, Wayne Rooney and Frank Lampard.
"He is just unbelievable, season after season he just delivers," said Mellor.
"It's not just the goals, it's assists as well, he is a joy to watch, fully fit, at it, just magnificent."
