Making my point here is going to take a bit of explaining. But when there's 100 things going on in a match (starting eleven, formation, subs, if the ref suddenly gives the opposition a harsh penalty, etc etc) you just can't use the result to get the whole picture. You can win the game even if you make bad subs. You can lose the game because of a bad VAR decision. So you need to keep them all in perspective.
I don't agree we were cruising around 70 mins. When Gayle came on, and Andy Carroll had that chance, McGinn was bit off the pace, and Hourihane was becoming quieter. At that time the game was in the balance then. Obviously it ended up not mattering (thankfully) but we could all have seen that match going another way. A bit like taking off Wesley and bringing a centre-half with 5 mins to go against Liverpool could have won us 3 points. It might not have worked but it sort of makes sense when you're playing the percentages. Not freshening up that midfield in the second-half wasn't playing the percentages today. We were lucky Newcastle were so crap that it didn't matter in the end.
