Adrian has quashed doubts among his Liverpool team-mates with his strong performances, a source has told Football Insider.
The Spaniard completed a hastily-arranged move in the final week of the transfer window after Simon Mignolet joined Club Brugge.
Alisson then picked up an injury in our opening game against Norwich to thrust him into the spotlight.
The source claims that there were concerns in the Reds camp about the ability of a player who had been released by West Ham United.
But he marked his full debut with a decisive penalty save to win Liverpool Super Cup.
And he has recovered from a poor error in the win against Southampton by putting in a series of assured displays.
Adrian suffered his first defeat between the sticks against Napoli, with his wondersave to deny Dries Mertens ultimately counting for nothing.
Overall, he has ‘blown away’ his fellow Reds and eased any fears that Alisson’s absence would have significant consequences.
Some are even thought to have concluded that he is an upgrade on Mignolet.
Whether or not this is a true reflection of the feeling behind the scenes, it seems the tailor-made, intensive training regime he underwent at Melwood over the international break is paying off.
