Fixed v fluid - the opposing approaches of Maresca and Carrick

There are many things that Manchester City and Manchester United have in common - but one thing decisively separates them this season.

Based just five miles apart and united by a shared desire to return to the top of the Premier League, their gameplans are almost diametrically opposed.

The best teams in the world often play in similar ways, as demonstrated in last season's Champions League final between between Paris St-Germain and Arsenal - teams who use similar shapes, look to dominate the ball, and encourage rotations into fixed positions.

But looking ahead to Sunday's Manchester derby, expect to see City boss Enzo Maresca and his United counterpart Michael Carrick field teams teams that play in a totally different way to each other.

In short, City use a rigid structure with players precisely positioned, while United have a more fluid approach that has some positional guidelines but allows players the freedom to roam - here is how it works in detail.

Maresca, inspired by mentor and former City boss Pep Guardiola, hopes to create a side synonymous with control, dominating as much of the ball as possible, looking to reduce the uncertainty that comes with playing football.

The Italian has often compared the move-based nature of chess to football, so it is not a surprise that positional play is the foundation of his sides.

These are ideas that have proved successful in modern football but Carrick's United deviate from this approach more than most.

This is not to say there are not positional ideas in Carrick's United.

There are, as we will go on to highlight, but they are certainly a smaller part of his game when compared to Maresca.

This balance is illustrated well in Carrick's quotes about how he first managed 21-year-old midfielder Kobbie Mainoo.

"I [was] really conscious of not giving him an awful lot [of instructions]," he said. "A couple of little pointers, a few positional things, but to trust in what he is. He's a fantastic footballer."

In United's midfield the deepest midfielder is tasked with helping in build-up play, either as part of a narrow midfield two - alongside United's second midfielder - or by dropping deep to create a back three with the centre-backs.

If the back three is created, the second midfielder holds his position in the centre of midfield alone.
