The best stat to measure goalkeeper performance is post shot expected goals (PSxG) vs goals conceded. PSxG is calculated by assessing loads of different factors like shot distance, angle, power, curl, and keeper position, and then compared against a massive historical database. It's more accurate than ordinary xG because it doesn't take into account the multitude of factors leading to the creation of the chance and instead focuses solely on those after it's been hit. For two seasons in a row, our Gav was bottom of the table for PSxG vs GA, and by some considerable margin each time. This completely supports the evidence of my own eyes, which is that he is a very poor shotstopper who rarely saves anything that isn't straight at him. But if you want to believe that he's just the very unfortunate victim of some completely made up stats - coincidentally two seasons in a row (what are the chances!) then you carry on. Oh but that's exactly what they are. It's a computer algorithm, and one based one based on very limited input data. The variance in output results is frightening. This is not a case of some team of experts analysing every nuance.

He's a strange keeper in that you cannot name a huge amount of howlers he makes (but he has made some), but on the flip side you can't really name any match winning or game saving saves he makes. As others have said, from a pure spectator POV and not on stats, you are often sat there after a goal went in and wondering ''should he have got to that?' - for one or two, yeah...debatable, but when pretty much every goal leads to those questions then you've really got to believe your gut. There's something not right there. The stats just backup what we've all seen to be honest. He lets in goals he should saved, not howlers per say, but a decent/capable keeper would probably pull of a 'great save' to keep it out. He doesn't seem capable of 'great saves', which is why he'll never really amount to much and why he shouldn't be front and centre for a promotion bid in any uncertain terms. There you go again. Trust your own eyes. Not some random number generating alorithm.
