A keeper is there as the last line of defence when everything else has failed. Other areas of the team may have made mistakes as well but the point is, his entire job is to bail them out more often than he lets them down. He doesn't do that.
Feel like Robinson is more of an Azaz replacement in the team, although admittedly we don't have another player that can fill the role Scienza does except Fraser and that's a massive drop in quality.
You can forgive him because it's 3-0, but Armstrong is passing up so many opportunities for players in better positions trying to get a speculative shot away.
Or, they were only a dozen games into learning a completely different style of play whilst either badly demoralised from last season or settling into a new team and so it took time for them to improve at it.
Hey ho.
