I think what he is saying is that Chelsea have lost a manager, lost their best player, lost their best central defender, lost 2 key midfielders to injury and haven't been able to recruit new signings yet are still above Utd in the PL who have spent reasonably well and only lost Lukaku and Sanchez who lets be honest wasn't any good anyway.
I would go on to say that despite this Chelsea have created a new team with very young players and with a new manager who has introduced a new attacking philosophy that promotes attractive football that just about everybody enjoys watching. Happy days at CFC against the odds while Utd suffer under better conditions.
You are forcing it to suit your argument. I could say the same thing.
What about us? We lost Lukaku our 2nd top scorer last season & also our best top scorer 2 seasons ago, we lost Sanchez, we lost our 2nd best midfielder Herrera, despite of losing those three we didn’t sign a replacement. We finished below you last season and we lost those three without a single replacement, in your argument it should make our team worse then. Why are you ignoring that?
We also lost our manager Jose Mourinho.
We lost Pogba our best midfielder and most creative player due to injury & we lost Martial our only centre forward due to injury, and I haven’t even include the others like Shaw, Tuanzebe and the others for injuries.
Why are you ignoring the fact that we also create a new team with very young player, in fact so far this season we have fielded the average of youngest starting XI, it wasn’t Chelsea.
Let’s be honest, Higuain wasn’t any good anyway. Oh by the way you did spend money on Pulisic and Kovacic. You are only looking at your situation but ignoring that United has been suffered worse.
