918 minutes is ten games. It’s not huge, but not useless either. besides, the people the wanted Zaha are nuts.
The thing about Lulz is the lack of joined up thinking. When he joined i looked into this a little bit and he was actually player of the season for Conte in a back 5. So if you use him properly, he is a big asset. Especially with his passing out of the back. Many teams now use the CB as DLP Using him a wide open back 4 with Sokratis and both fullbacks bombing forward and screened by Xhaka? So yeah - i bet Luiz would also do OK if the backline sat far more, we were compact and played a low / medium block that would also help our transitional game which suits players like Willock, Pepe, Auba etc
The utility of data depends on for what it’s used. Here, I’m using a limited dataset to show that Arsenal were correct in choosing Pepe over Zaha. This obviously doesn’t mean that I can use the same dataset to show that Arsenal were right in signing Pepe.
