An example was already given in this thread. While we don't know if it was or wasn't a factor in the team's decision making, you can clearly see its value where it (retrospectively) was clearly able to show that Ryan wasn't performing. Onces Sanchez came in, we saw an improvement. Ryan wasn't able to get back into the team and was eventually shipped out. As I say, don't know if the team uses it or not, but it's *plausible* that it may have played a role in identifying the need to make that change.
Also, re: that Maupay quote: IIRC he made it in the middle of his lean spell last season. Of course he labelled it bullcrap - it was making him look bad. Suspect his opinion would shift pretty quick if it was the other way around and making him look a world beater.
OK - thanks!
Perhaps I should remind myself from time to time that the 'everything is rubbish today' brigade are usually wrong
