Manchester United picked up a point against the Premier League leaders on Sunday afternoon, with Michael Carrick taking charge of his second match as caretaker manager.

The caretaker boss opted for 4-3-3 as his formation on the day, which was a surprise departure from the 4-2-3-1 most regularly used during Ole Gunnar Solskjaer's reign.

On the back of the switch, Carrick was asked whether Ralf Rangnick - who is United's new interim head coach - had any influence on the tactical decisions before the match, but he responded with a firm denial.

The German may not have been involved with the specifics of the contest but regardless, Carrick might have provided him with a fresh idea from upon which to build, with 4-3-3 as United's new go-to shape.

Fred, Scott McTominay and Nemanja Matic were selected to occupy the middle of the pitch at Stamford Bridge, and although they could have contributed more when in possession at times, they competed well on the defensive side of the game and generally maintained a presence throughout.

It remains to be seen what Rangnick will do once he assumes control, but based on the make-up of the squad as well as the team's general performance against Chelsea, 4-3-3 could be worth keeping.

United have a wealth of wide forwards in their squad including Jadon Sancho, Marcus Rashford, Anthony Martial, Mason Greenwood and Cristiano Ronaldo, with the latter two also able to operate through the middle.

Players such as Bruno Fernandes, Donny van de Beek and Jesse Lingard are recognised as no.10 types which could be problematic within the confines of 4-3-3, but they could adapt to form part of the shape.

Both Fernandes and Lingard have led United's line in the past - with the Portuguese doing so in the majority of the clash with Chelsea over the weekend - and the pair also have the capacity to play in central midfield.

Van De Beek has some experience as a central midfielder, and Paul Pogba could benefit from an additional teammate in middle given his struggles as part of a midfield duo in the past.

Difficulties would likely be encountered if those attack-minded names played together as a trio, but with one of them alongside two of Fred, McTominay or Matic, Rangnick could strike a fine balance.

Ultimately, although Carrick's brief time in charge is coming to an end, the Englishman could have inadvertently provided Rangnick with a platform from which to work.
