Here is what our Chelsea fan writer Ross Mooring had to say in response to questions from our Manchester United contributor Dale O'Donnell.

Do you think Enzo Maresca needs to do extra homework on Manchester United now Erik ten Hag has been sacked?

While I am sure Maresca will be looking at the win over Leicester and Ruud van Nistelrooy's past games as manager, the Italian is still very much bedding in his own style of play at the club.

He also has to be concerned that the Blues have only kept four clean sheets so far this season and none in the past seven games, in spite of some relatively easy fixtures in Europe and the league.

What are your thoughts on Jadon Sancho at Chelsea?

Sancho has started brightly in a Chelsea shirt, assisting in his first three games and offering something on the left flank that none of the other options at the club do.

However, he was subbed off at half time of the defeat at Liverpool and has not featured since, partly due to illness. Not being allowed to play against his parent club regardless, I would expect Pedro Neto will start on the left wing with Mykhailo Mudryk the alternate option.

What are Chelsea's biggest strengths going into the game at Old Trafford?

It might seem too easy to simply say "Cole Palmer" but it is the truth. Since the moment he signed on deadline day last year, Palmer has played in the manner of club legends Eden Hazard and Gianfranco Zola and he scored more goals last season than either ever achieved in a blue shirt to boot.

While both Moises Caicedo and Nicolas Jackson have added composure to their games this season and Englishmen Noni Madueke and Levi Colwill have improved too, it is Palmer who will constantly be occupying two or three Manchester United players at a time on Sunday.
