Virgil van Dijk has been an absolute revelation since arriving at Liverpool for £75m last January.
A side that was once laughed at for having one of the most unreliable defences in the country now sits with a proud record of just 7 goals conceded in 18 games.
Van Dijk has been a huge part of that - Liverpool have kept as many clean sheets since he arrived than they've conceded goals.
The Dutchman's performance against Wolverhampton Wanderers on Friday went some way to encapsulate what he brings to Anfield.
Van Dijk was assured at the back, winning headers and interceptions, while also outpacing Adama Traore and scoring his team's second.
It was a complete showing from Liverpool's number 4 and one that rightly drew praise from all quarters.
One of those who has praised Van Dijk in the wake of the Wolves game is Jamie Redknapp - and he gave fans something to talk about.
Redknapp wrote in his column for the Daily Mail that 'nobody comes close to Virgil van Dijk in the race for the player of the year'.
That's a strong statement, although one that it's probably just about reasonable to hold.
His next statement, however, not so much.
"Think of the best defenders in Premier League history — John Terry, Rio Ferdinand and Nemanja Vidic," he said, before adding: "Van Dijk is all three players rolled into one."
Now that's quite outlandish.
Unsurprisingly, rival fans had quite a bit to say about Redknapp's comparison there - you can't really blame them for reaching the end of their tether with the Van Dijk love-in.
Van Dijk is undoubtedly an outstanding centre-back and is firmly in the argument for 'best in the world' right now.
But to compare him to legends of the game like that is taking things a few steps too far - he's got to accomplish more to be in that bracket.
And it's safe to say that most fans would agree.
