Carlo Ancelotti is a manager that needs no introduction.

His career has spanned 25 years across ten different clubs, and has seen him lift the biggest prizes in world football.

But while the Italian is a well-respected tactician, what is his long-term vision for Everton?

The Italian has, after all, been flexible throughout his time in management.

“There is more than one way to play football,” Ancelotti said. “I like all styles. There is no winning system. If I have different players I could play a different system. Football has changed, a lot more intensity, more tactical knowledge and the rules.

"How many teams build up from the back now? Nearly everyone. If you want to play long balls and fight for the second ball, that is football. If you want to play catenaccio and counter-attack, it is football."

We studied some of the most prominent systems and formations that Ancelotti used to see how they might apply to Everton.

4-4-2

This is a formation Ancelotti has used for long stretches at Reggiana, Parma, Napoli and Paris Saint-Germain. It defined his early career, and it is a system he has also leant on with Everton before changing recently.

Often with the Blues it involves Dominic Calvert-Lewin and Richarlison operating as the front two.The Italian did adapt his 4-4-2 formation while at PSG to sit his two central midfielders in a slightly deeper role. Sometimes referred to as an ‘empty bucket 4-4-2’ it would be possible for Everton.

Both Allan and Doucoure have served as more defensively minded midfielders and this would afford more freedom to the full-backs to join in with attacking play if Ancelotti wanted to maintain a sense of structure.

In this system, James Rodriguez is utilised out-wide but allowed the freedom to drift inside naturally.

4-3-3

This system was one that Ancelotti used at Chelsea, Real Madrid, Bayern Munich and PSG.

Once again, like his use of 4-4-2, he was not afraid to make small tweaks. In this instance, the midfield three was inverted from one defensive midfielder and two in front, to use two behind one leading central midfielder.

This is certainly a popular formation in modern football, and it could also allow Ancelotti to move Godfrey into defensive midfield if needed, with Allan and Doucoure serving as dual box-to-box midfielders.

While on paper this may also see a traditional front three, it’s more likely that Richarlison would sit narrower, near to Calvert-Lewin, and form a striking partnership, with James also drifting centrally at points.

4-3-1-2

This is the classic formation most people think of when they discuss Ancelotti’s Milan side even though he first introduced it with Juventus.

The system would place James Rodriguez in the hole behind a strike duo, and then a midfield three behind them.

Andre Gomes could operate as the middle-man looking to recycle the ball, while Allan would be the Gennaro Gattuso in this situation. Alongside him, Doucoure would be tasked with contributing on both sides of the ball.

Explaining his switch to 4-3-1-2 while at Juventus, Ancelotti said: “Zidane changed everything, because I placed the team around him. I tailor-made the side for Zizou. He changed my style of football. I owe everything to him.”

3-4-1-2

There is a lot to like about this system from an Everton perspective, one that Ancelotti used during his time with Juventus.

This would allow James to sit behind the strike duo, and Coleman and Digne to do their best work in the final third.

The great strength of this system is the potential versatility. It can overwhelm the opposition quickly on the counter-attack, but against elite sides it can bunker in and provide tremendous defensive structure and shut off space.
