Seen some discussions on here regarding our defence and the quality/ quantity of chances we give away compared to other teams. Looked into some xPG data to do some basic analysis of this. Basically this data tries to predict the chance a certain shot will be a goal based on a whole load of different parameters which gives each shot a xG value, a larger value indicates a higher probability of being a goal. Probably plenty on here know much more about it than I do. Originally I had hoped to make my own fancy tables but struggling to find any current data for this season that is publicly available, so relying on others for this basic comparison. So to begin with this is every goal we have conceded in the league this season. City Goals Conceded: From a very quick glance we can see the majority of our goals conceded are from relatively low value shots, indicating goalkeeping errors are leading to low probability shots going in or players are scoring great goals against us. Now lets compare that to say Tottenham, one of the best defences in the league. Tottenham Goals Conceded: This shows the majority of their goals are conceded from high value chances with few low value goals being conceded. This would appear to indicate when they concede it is due to defensive errors / good opposition attacks leading to high quality chances which leaves a keeper with not much chance of making a save. This quick glance between the two would seem to indicate we give up less high quality chances than one of the best defences in the league. This would also suggest our defence is doing a good job on the whole and a better shot stopper in goal would make a big difference. A quick comparison of the goals conceded by Willy and Bravo. Willy: Bravo: This highlights how Willy's apparent better shot stopping ability has lead to fewer low value shots being conceded (although he has played fewer matches) compared to Bravo where nearly all goals conceded were lower value and should in theory be savable to some degree. This doesnt show if we are giving away good chances that we simply save however. Again I will compare to Tottenham. City Saves: Tottenham Saves: Tottenham have more high and medium value shot saves which shows our defence gives up less chances than theirs with Loris being the main factor between the goals conceded, particularly for shots just inside the 18yard box where Bravo has conceded most of his goals yet Loris appears to save. So in summary: We give away not only less chances in total but less high value chances than one of the best defences in the league with most of our goals conceded coming from low chance shots from around 12 yards away from goal which have since stopped since Willy has been in goal. This suggests either they are brilliant goals or a better keeper would manage to save them. In theory if Willy had played all season the majority of our goals conceded would have been saved if current trends were applied. This does not account for the fact Bravo played when the team was in the process of learning new tactics which I believe lead to more chances from around the 12yard range, chances which have since been reduced, nor the positives he provides in possession of the ball. That was a quick run through of the stats on our goals conceded, hopefully its interesting to some people. If anyone interprets things differently just say, that is just how things appeared to me. There is so much more that could be shown like individual games or comparisons to other teams but that would be so much to post at one time. https://public.tableau.com/profile/...ueShotDashboard2016-17/PLShotDashboard2016-17 this is where I got the data from so have a look yourself if interested.
