One great thing is how good we have become at protecting leads. I remember plenty of late goals to gain or secure points (most importantly Chelsea this year), but it's a long time since we conceded one. We have learnt how to shut a game down efficiently, and I always feel in doing so, we might nick an extra one on the break as we did at Newcastle, Roma and Southampton for instance.
I can't say I felt relaxed going into the last 15 mins yesterday, but I was quietly confident that we would see it through.
