One of those saves (assuming you're referring to the three saves from I think successive corners) was a block from Manning, not a save from Bazunu. The first one was a good save alright. Then he's too weak for the second goal (from a cross, of course). There's no foul there for me; just someone standing in his way.
Interesting that the same was the case in the previous match against Birmingham too. What looks an unstoppable (well, except by Farquharson
maybe) shot is only made look that way because Bazunu was on his near post for a central shot, so he's offering the whole far side of the goal up. There's a
screenshot posted on the Southampton forum (and normally I hate screenshots, but as a positioning point in time this one seems appropriate). File is quite wide so putting the link in instead.
Drops to the bottom of the Championship in terms of PSxG performance - and that's even allowing for the fact that Southampton's open defending leaves him facing tougher shots than almost every other keeper.
