Probably a daft question but what difference would it really make if they did? Would almost everyone not still refer to the stadium as Old Trafford? You can point to a number of renamings of sporting arenas and people still use the old name colloquially even if the "official" terminology is now different.
I'd agree it might leave a sour taste in the mouth but in terms of actual effect it seems likely to matter little.
It wouldn't really make a difference but it still wouldn't be the same. I'd just rather it didn't happen (and it doesn't look like it will, anyway).
Apparently, this is the list of RvPs injuries for anyone that's interested.
I'm pretty sure if you put every single injury, however minor, in a list, you could make any player look dodgy.
