Lallana will play for Brighton after leaving Liverpool

So again, the quality of the shot is not taken there, so it does not completely indicate the quality of the goalkeeper. For example, the first 2 goals of Liverpool were I guess 0.04 or 0.06 together, but they were relatively heavy shots. Yes, I would expect him to catch at least one goalkeeper, but it’s not like he should have these two shots in 99.5% of cases (which xG really says).

The statistics for the goalkeeper are a bit unfair, because only the place from which the player shoots is taken into account, ie how good a chance the team will build. But it is not decided if the player does not hit the goal, hits the crossbar, shoots the player, shoots it in the middle of the goal or that the ball is barely hit there. Or it’s a great shot under the crossbar, where the goalkeeper has to show himself. And all these bullets have a distance of, for example, 0.02, because a good shot will make 5 out of 100 attempts and maybe 1x is elusive.

An example of Robert Carlos’s straight – there would be xG maybe 0.0001 . But this shot was in such a style that it was extremely difficult for the goalkeeper. Was she caught? Probably yes. If the goalkeeper caught it, would he deserve a 0.0001 post shot xG statistic in his favor?

Or xG for a penalty is always 0.76. Do the goalkeepers really catch a 1/4 penalty or does it also count that it goes into the stick or completely off? Or that the player kicks it badly and goes slowly to the middle.

Until the quality, location and strength of the projectile are evaluated in the statistics, it will not be entirely meaningful to the goalkeeper.
