Costa is one of the best strikers around, while we are witnessing Zlatan's decline in a very physical league. Matic provides consistency, fluidity and is reliable defensively, while Pogba is a non-factor when he is not in a well oiled midfield like our old one. Martial vs Pedro, Martial would be the wise choice however Pedro's experience and tactical intelligence has been invaluable in almost every side he's been, that would make it very hard to overlook him for an unexperienced, inconsistent youngster.
Conte has the better trio and that trio isn't on it's own, Matic is partnered by Kante and Luiz coming up to provide more presence, Pedro compliments Hazard who was known to be inconsistent and a flat track bully, Hazard-Costa-Pedro is a fearsome trio backed with competent wingbacks.
Chelsea doesn't have just a trio, they've got a team. Man U barely has a trio, they've got a bunch of confused individuals.
