I am sure you just forgot, that they not only lost VVD but also most of the rest of their CBs. I don't have any compassion with them, feck them, it might have been their managers fault as well to an extent seeing that their young CBs are doing just fine these days, re-shuffling their whole team was too much. Nevertheless - the original point was, they were severely weakend by injuries. While we were relatively lucky with major injuries this year. Sometimes your lucky, sometimes you aren't. But I don't see the benefit of downplaying the effects of an injury crisis. As Manchester United, we should know better about this.Their most important player who was also a part of their team who shipped 3 against Leeds and 7 against Villa, that guy? Of course, it's all hypothetical from your end, but they had some shocking defensive performances after lockdown with him in the side as well...
Controversial thought: the question of the OP was about the extent of progress we have made. I understand you clearly recognize progress and the extent of it is... big/really big/magnifiecent/significant? Correct me here, about the extent. I interpreted your texts that you consider the progress (at least) as significant.With that being said, we need more because certain players are starters when they really should be squad players and bringing those upgrades in will see a further progression of the team. I'd say we're 4 top quality additions away from being a complete team, but just getting in two of those players would see us come on leaps and bounds.
My question would be, if we are 4 quality additions away right now, did you consider the Mourinho team as 10 players short? Genuine question, not a trick. I think, this might be one angle to discuss the actual extent of progress.
