Grant’s record against Man U: 1 win / 1 loss
I think Jose Mourinho, the ex-Chelsea manager, had a good record against Man U.
Chelsea might have a “home-field” advantage...
Grant’s loss was his first game in charge (at 3 days notice) of a team that was in shock at the departure of Mourinho. Being put in charge of a team and then sent straight to Old Trafford is about as bigger baptism of fire you could conjure up.
Chelsea’s good record v Man Utd pre-dates Mourinho. Chelsea have the best record of any team visiting Old Trafford. Man Utd have a poor record at Stamford Bridge.
So considering it’s a neutral venue, taking the away form v each other, Chelsea have the edge.
