Personally either Mertesacker/Kosc or Terry should have partnered Cahill in the PFA team of the season.
In fact all three of them merited more inclusion than Cahill, although you can't argue with Cahill there too much, but Mertesacker, Kosc, Cahill and Terry are the only CBs who should have been considered. Although saying that I think the heavy defeats didn't help your cause.
Shaw should have been nowhere near the lineup though. Azpi easily has been the best LB in the league this season. Rock and a half.
