The boss has been demanding clean sheets from his side, after only four in 27 matches in all competitions this term, and was particularly angry after a topsy-turvy 4-3 win at Reading. Following a pulsating victory against Newcastle by the same scoreline on Boxing Day, the entertainment is showing no signs of abating.
Although many would appreciate things tightening up in defence, not least for the blood pressure, there is no disputing the excitement that is being produced by the Reds this term with West Brom next on the agenda.
When asked on Friday about how United stop conceding so often, Sir Alex told reporters: "I can’t answer that. I can’t possibly answer it. Obviously, I don’t think we’d be doing our job properly if we weren’t assessing where we’re losing goals. We’ve been analysing every possible detail to try and get a constant thread that tells me we need to do this but that just doesn’t appear.
"Either we don’t attack, which is not United’s way, or we have to let our supporters live through the agony of 4-3s. We’ve not had a 5-4 yet or a 6-5. I think that would be even more exciting! I said after Reading it had to stop. And I’m saying it again – it has to stop. But it won’t stop. With this present team, it’s just one of those seasons where we seem to be letting in silly goals."
