Save % and xG Conceded
To start with, we will be taking a look at the most conventional metrics in terms of shot-stopping.
Save percentage-wise, there is very little between the three of them. This season, Onana has saved 73.5% of his shots, Kepa was ever so slightly lower at 73.3% while Mendy managed 75.5% during the 2021/22 campaign.
However, if we compare the actual goals they let in compared to the post-shot xG conceded, we see a clear winner among the trio.
Kepa has a +5.0 score, with Mendy (-1.6) and Onana (-.2.7) trailing. It means Kepa is better at saving shots than the average keeper, while the other two shot-stoppers are not (based on recent form).
