Since signing and appearing on the bench in the days that followed, the 25-year-old has been a lesser-seen commodity on matchdays.
However, Mellor still holds out major aspirations for the centre-back and he told the Liverpool Echo his future remains bright.
“For me, [Davies] is a player that I have always believed can play in the Premier League and I am absolutely delighted he is going to get that opportunity and now it is up to him to take it,”
“This kid can play for England if he really grasps it. He is not someone who was a stop-gap, he could potentially, long-term, be the answer and that is up to him.”
Well, positive affirmation Liverpool will eventually see a high-quality performer when Davies makes his long-awaited debut.
In truth, whilst the immediacy of the situation meant the clamour to see the £1.6m man was through the roof, Klopp holding players back and allowing them time to settle is nothing new.
Hopefully, Mellor is proved right and the Reds have found an unlikely long-term solution.
