Fabinho's slow start at Liverpool is being quickly forgotten thanks to his display against Manchester United.
In truth, the Brazilian has been looking more comfortable at Anfield for some time now, but his masterclass in that 3-1 victory - and in one of the biggest games of the season, too - has now cemented his reputation.
It took a long time for Jurgen Klopp to be convinced of his fitness, as is often the case when players arrive from Ligue 1.
Indeed, Fabinho didn't make his long-awaited debut until October 20.
What he did display at Monaco, however, was his versatility.
It was one of the reasons he was so in-demand when he left the principality, and why Liverpool were willing to fork out £43.7million for his services.
The midfielder played in various positions under Leonardo Jardim, including at right-back and in the heart of the defence.
Fortunately, there has been no need for such rotation on Merseyside.
Klopp's men sit top of the table by a point partly thanks to their strength-in-depth - and, in particular, their improved defence.
Nevertheless, injuries are beginning to take their toll.
Injuries are mounting
First, Joe Gomez, who has been thoroughly impressive this season, suffered an ankle injury against Burnley.
Then, in the Champions League victory over Napoli, Joel Matip fractured his collarbone, leaving Liverpool reliant on Virgil van Dijk and Dejan Lovren - their only two fit senior centre-backs.
Klopp is therefore hoping Fabinho can fill in at centre-half if needed against Wolves.
“I hope Dejan can play them all but I don't know in the moment. It looks really good,” Klopp said, via the Liverpool Echo.
"We don't really have options. But Fabinho can play at centre-half as well so that's good.
“Nat Phillips is injured as well which is a real shame. We may have to think about other options like three at the back with two midfielders or stuff like that.
“If something else happens we would have to do something like that. When I saw the Southampton v Arsenal line-ups I saw Arsenal are already in a situation where they have to make these changes.
“It's just the situation and the job to do. If we can keep them fit it's very important but who knows?”
So, it could be an unusual line-up that takes to the pitch at Molineux tonight.
As Klopp points out, Arsenal have found themselves in a similar situation - but Unai Emery's progress has been derailed somewhat in the last week with defeats to Southampton and Tottenham.
Liverpool can't afford to give Manchester City an inch over the festive period.
