Moyes set his stall out when Heitinga came on. At the time we had 7 out of 10 outfield players as defenders so it isn't surprising the game went that way toward the end.
Luckily it paid off as there would have been a lot people peeved with Moyes had we let the win get away.
Shame we couldn't gone on to have a more comfortable game, but we're on 40 pts now so that should be cause for some celebration (albeit a bit of a low bar but given our season its a very welcome milestone).
It was a pretty good first half though, and glad we didn't concede as usual at the 20 min mark as that would've meant we ended with another draw.
