So when teams sit deep against us and we can't break them down it's because of our vulnerable (according to you) defence?
It's more to do with the fact that we don't have creative players on the pitch (Pogba injury) and a clinical striker. When Bruno came in and was the source of the creativity we looked much better, it wasn't a coincidence.
Saying we need to play limited players is garbage. Without Pogba in the team, we basically had no one in midfield that could create until Bruno came in. That's not the same as sacrificing attacking players for more defensively minded players so don't try and spin it like that.
De Gea, AWB, Lindelof and Maguire have been the players with the most minutes this season and as a unit has been very solid. Backed up by the stats. They've held up their end but the creative players haven't.
We don't have creative players on the pitch because the hard workers are taking their place, presumably to shore up the defence. If Ole trusted the pair of Maguire and Lindelof, then I don't see why he would favour the hardworking duo of Fred and Scott over the duo of Pogba and Matic which has more guile.
Players like AWB, Scott, Fred, James, etc have been played to make sure we're decent defensively, and IMO Ole shares a lot of the blame as his setup isn't good enough, but also the CB's do seem to need a lot of protection to come away with those clean sheets being boasted about. I think the best course of action is to start Matic, Pogba, and Bruno, and tweak the defence until we find a combo that can cover for that midfield, instead of playing midfielders and even attackers to cover for the defence.
