Standing on the sideline, Ruud van Nistelrooy could hardly believe what he was seeing. Less than a minute into the game, his Leicester City side were already 1-0 down to Everton at Goodison Park.

By the time the clock hit six minutes, the Foxes were 2-0 down, and it was already a case of game over. And while Van Nistelrooy looked shell-shocked, David Moyes could not hide his delight at what was unfolding.

“I was thinking. ‘My goodness, this is fabulous,’” the Scot remarked afterwards. “If you’d given me three wins out of the four games we’ve had at the moment, in the position we’re in, I’d say thanks very much.”

Van Nistelrooy tried his best to rally his side, but he spent most of the opening 45 minutes standing frozen on the sideline, no doubt struggling to comprehend the horror show that was unfolding in front of him.

Things went from bad to worse for the Dutchman as his side headed into the break 3-0 down after Beto struck for a second time. The manner in which the goal unfolded was embarrassing for a Leicester side that were struggling to do the basics.

Leicester’s misery was compounded when Iliman Ndiaye added a fourth on 90 minutes after more hapless defending. Van Nistelrooy simply had no answer.

But as Blues supporters headed for the exits safe in the knowledge that their side are easing fears of relegation, this result served as a reminder of why it is important to get in-season managerial appointments so right.

Leicester have won just one of their last 10 league games and have shipped 24 goals during that spell. The Van Nistelrooy experiment is failing, and it is failing badly.

When The Friedkin Group opted to part company with Sean Dyche, everyone had their say on who should succeed the 53-year-old. Some felt a young coach was required, some wanted the Blues to think outside the box, while others wanted the return of Moyes.

Very quickly The Friedkin Group opted for Moyes. He was quickly dubbed the safest pair of hands Everton could have gone for.

But after four games, that almost feels like an insult to Moyes. He is already showing why he enjoyed so much success during his time at West Ham United.

The same cannot be said about Van Nistelrooy, who looked out of his depth at the weekend. And it wouldn't be far-fetched to suggest that Dyche could end up in charge of the King Power club by as early as the end of this month.

When it came to managerial appointments, Farhad Moshiri, more often than not, got them wrong. Hence why he went through so many managers during his time as majority shareholder.

The timing of Dyche’s departure looked odd, but The Friedkin Group acted decisively. They have since been rewarded for the call by how well Moyes has done and the upturn in results and performances his arrival has brought.

And if The Friedkin Group needed any more evidence to justify their decision to part ways with Dyche and bring in Moyes, then it arrived on Saturday.

Van Nistelrooy's men played like a side that had already accepted their fate. They look destined to be heading back to the Sky Bet Championship at the end of this season.

The same, though, cannot be said of Everton, who, with a couple more wins, can start planning for life at Bramley-Moore Dock as a Premier League club.
