Carlo, as the banners say, is magnifico. The Everton manager is one of the very best. Since he walked into Goodison Park he has transformed a team that was sinking under the weight of expectations and failings of his predecessor Marco Silva.
Ancelotti is a master — of that there is no doubt. But the Italian is also human — and therefore capable of error. As you’d expect from a tactician of his experience and wisdom, he has rarely been to blame in the 11 games Everton have lost since he took charge almost a year ago.
But on Saturday night against Leeds, as at Newcastle at the start of November, the signs suggest that the manager simply got it wrong.
His counterpart Marcelo Bielsa demurred when it was put to him afterwards that he had got the better of the former Real Madrid manager, preferring to praise his players. But of the two formations and systems on show at Goodison it was the Argentine’s that seemed more effective and cohesive.
Of course the home manager was fighting with a hand tied behind his back. He had only just finished trying to make do without one of his most influential players in Richarlison recently, when injury struck another of them.
It was always going to be tough to replace Lucas Digne. But the Italian has faced that tall task already, at St James’ Park on November 1. His answer then was to use the potential and pace of Niels Nkounkou at left-back in a back four.
It didn’t work. Everton were awful and the 20-year-old Frenchman was withdrawn for Cenk Tosun in the second half.
But perhaps taken with how well Alex Iwobi performed as right wing-back in place of Seamus Coleman, another costly absence, at Fulham last time out, Ancelotti arguably fell foul of muddled thinking.
He kept the 3-4-3 formation that allowed Everton to outscore (and also concede twice) against the west Londoners, but swapped Iwobi to the other flank and asked Tom Davies to play as right wing-back. For different reasons than on Tyneside, this reshuffle didn’t work.
Everton are one of the best teams in the Premier League at getting crosses into the box and scoring from headers. It’s partly what has propelled Dominic Calvert-Lewin to the top of the division’s goalscorer table.
So often the deliveries come courtesy of Digne and Coleman overlapping Richarlison and James Rodriguez respectively and firing balls into the young England centre-forward.
At Craven Cottage, Iwobi managed five crosses, and Digne seven.
But on Saturday night, Iwobi was always going to have a far harder balancing act; tasked with getting his defensive duties right in the face of Raphinha down his side and Leeds’ incessant attacking.
Consequently the Nigerian produced just two crosses all game. Davies only one. The average position map from Opta below shows just how deep Iwobi (Number 17) played, with 24 of the former Arsenal man’s 39 touches overall coming in his own half.
Davies fared slightly better. Of his 33 touches, 16 were in his own half and 17 in Leeds’ but if the pair’s deployment was intended to continue some form of supply line to Calvert-Lewin, it failed.
Ancelotti put a brave face on it afterwards, insisting the wing-back formation was not the reason his side lost.
“Yes we missed some players and we need to adapt,” he said. “But honestly, they adapted quite well and the work of the wing-backs was really high. [They had] good fresh legs and the performance of both of them was, in my opinion, good.
“I think we played badly against Southampton and Newcastle but tonight it was a good game… not enough to win but we competed. If we could score before [first] we could win.”
The Everton manager was correct in that neither Iwobi or Davies were the reasons the hosts lost again, after appearing to turn a corner, albeit in a faltering manner, in London.
His team’s problems were more than just two square pegs forced into round holes because of injuries. If the formation was also intended to ensure Rodriguez was still free to roam in the attacking role which lit up the start of the season, that didn’t quite work either.
Either sticking with the 4-3-3 which made Everton’s start to the campaign so scintillating, albeit without two key cogs in his full-backs, or returning to 4-4-2 and making the Colombian adjust his role may well be better options.
Instead it was a helter-skelter evening when Everton fell too easily into the trap of trying to out-attack Leeds instead of playing their own game.
With his first anniversary approaching, it feels like Ancelotti is still trying to learn his best way of playing when he can’t play his strongest XI. Still learning about which players he can trust; not, it would seem, the raw but promising Nkounkou, Anthony Gordon or Jarrad Branthwaite.
Indeed, he is still mulling over his best defensive pairing, and the chopping and changing of his centre-backs can’t help the need to stop conceding so many goals.
It was perfectly understandable for the worryingly leaden Yerry Mina to sit this one out. In came Mason Holgate, who in turn sat out Fulham after a poor return from injury in the defeat by Manchester United.
On Saturday night Holgate, wearing the captain’s armband, was the centre-back to make way when the manager wanted to try something different and bring on another attacker in Bernard.
The truth is Everton are still lucky to have Ancelotti. They’re undoubtedly on a better path to potential success under a steward of his wisdom and guile.
But imagine, for a moment, if this confused and frustrating performance had come under Silva. Ancelotti has seen it all before and won’t lose much sleep over criticism.
He’s also far too savvy than to list his team’s tactical faults too painstakingly in the aftermath of defeat.
Whichever way you cut it, it felt like he got it wrong on Saturday. That’s not something you can say very often of the manager who has won more trophies than most.
But Everton were always going to be one of the toughest challenges he has faced in his managerial career. Their long-suffering fans must at least hope a man who makes so few mistakes, doesn’t make his latest ones twice.
The players he has at his disposal seem so much more suited to a back four. If the wing-back experiment is to continue, then his other players must become far better at replicating what injuries have taken from this team.
