Mcshane was awesome against spurs and was solid during pre season when i saw him. Nyron on the other hand...he also played awesome against spurs and was solid last season, my only worry is he sometimes thinks he's been blessed with the skills of a brazilian and does tend to loose the ball in these moments of madness (which all tend to be deep inside his own half).
i haven't seen much of Anderson but people i've spoke to reckon he's a solid, no nonsense defender so i suppose we have him too fall back on if nozza goes nuts
