Arne Slot just did something in two months that Erik ten Hag still hasn't after two years
It's usually a good day when Liverpool wins and Manchester United doesn't, and that is a fairly common occurrence these days given the contrasting fortunes of the two greatest clubs in England.
The 1990s and 2000s were undoubtedly United's, but Sir Alex Ferguson's 2013 retirement signalled the end of an era of dominance for the Premier League's most successful club.
Manchester City took United's place as the dominant outfit in England, but Liverpool has not been far behind in recent years, winning the title four years ago and taking the title race down to the final day of the season on two more occasions.
Arne Slot has already surpassed Rafa Benitez and Jurgen Klopp
Real Madrid star Rodrygo has already revealed why he rejected Liverpool move
United's latest steward, Erik ten Hag, started his time at the club promisingly, but the Red Devils have regressed over the last year or so, and there are plenty of calls from supporters for him to be sacked.
The fact that Liverpool is doing so well under Arne Slot only rubs salt into United's fans' wounds, and against West Ham on Wednesday Slot proved why he is in a class above his compatriot.
While Ten Hag is yet to instill a clear identity in his United team, despite taking charge well over two years ago, Slot's fingerprints are already all over the Liverpool team.
Plenty of Liverpool's players have specifically spoken about how the team's style of play has changed slightly since Slot replaced Jurgen Klopp, with a fair few of them stating how much they are enjoying playing with more of an emphasis on controlling matches.
Against West Ham in the EFL Cup, Slot fielded a much-changed team for the first time this season and still managing to get a tune out of what many would regard to be a second-string side.
A few dozen miles down the M62, meanwhile, Ten Hag was watching on as his United side delivered another predictable performance and failed to claim three points in its Europa League opener against FC Twente.
Few United fans would admit it, but there will surely be plenty of them who are currently thinking that the wrong Dutchman ended up at Old Trafford.
