Thanks for the confirmation on March. It all pointed to an ACL, but this is the first reputable indication of it.
Potentially this also comes from a recent Naylor article (or tweet): Welbeck's injury is hamstring and his return is currently scheduled for January -- can you verify this?
A few things on this:
-- the VAR breaks are causing long pauses but, then again, they've been doing so for a few seasons, so there's not much difference there ...
-- ... the clampdown on time-wasting is new this season and might be an explanation, but I suspect I'm not alone in thinking that...
