Of course Pedri is missed but it also plays a part when large chunks of when he was missing last season was when club were a shambles and had others like Dembele out, Koeman was dead in job and have front lines of LDJ, Abde, Jutgla etc.
Same as this season. Out same time as Dembele and others.
Of those stats he is the player that will make one of the biggest differences no doubt. Would be him and Dembele and been out a lot together past couple seasons.
Also helps when play every game that Messi was still at club in his first season to boost how team performs with him in it. Those stats will show as if that was all on Pedri and igore Messi etc impact.
Likes of Gavi, Kessie and Roberto are huge drop offs from job Pedri does... FDJ better than all three but not as good as Pedri higher up but then you have issue of Robert, Gavi and Kessie not being able to do what FDJ does deeper either if move him.
Dembele and Pedri are Barcas two most important players in final third and one/both being out makes a big difference but even outwith that it is nowhere near as simple as comparing stats solely with Pedri in and out of team. When 40/50 of those games he plays Messi is still at club and months when he misses is worst time for club and quality of players in years last season.
