Since Carlo Ancelotti's arrival as Everton manager, things have begun to look up a lot more for the Merseyside club.

Barring the rather surprising catastrophe against Chelsea last weekend, the Toffees have enjoyed an impressive revival under their Italian boss - their only other Premier League defeats coming away to Manchester City and Arsenal respectively.

And one of the big reasons behind that, is the form of both Dominic Calvert-Lewin and Richarlison. Ancelotti's touch of magic has seen them operate as a strike duo for Everton under his leadership, and the goals have been flowing for the both of them.

Calvert-Lewin has arguably outshone his Brazilian teammate, scoring eight goals in 12 games, whilst Richarlison has managed four in ten. It has been quite the old-fashioned feel to the way Everton have lined up in recent weeks, with the Toffees opting for a version of the 4-4-2 in each of their last eight games in the Premier League.

But whilst they have had some notable results - not least their dramatic 3-2 victory at Watford - it has also proven to be their undoing in their last couple of games. First, they fell to a narrow defeat to Arsenal, before drawing 1-1 to Manchester United, and then getting hammered 4-0 by Chelsea.

In the games where they are more confident in their own abilities and feel they are the stronger team of the two, then the formation naturally lends itself to a positive result. But in games where the opposition are likely to dominate the possession, the 4-4-2 can really hurt them in trying to win the all-important midfield battle.

In Everton's last three outings in the top-flight against Arsenal, United and Chelsea, they have averaged 49%, 44% and 40% of the ball respectively. It's one of the big factors behind why Calvert-Lewin was such an anonymous performer last weekend - the Toffees simply couldn't control the match enough in order for him to get the ball.

So in essence, Ancelotti's genius touch in unleashing his two most prominent attackers as a strike partnership, has left Everton in a catch-22 situation. They'll be a major threat to all the sides they should be beating, and slightly more open to the teams they should be looking to compete against.

Meanwhile, Everton must sign star hailed by Ancelotti as a "complete footballer".
