Tbf, KDB has been poor this season. Is his normal pass accuracy the same or worse than Fernandes'? And TAA's stat is again very misleaing - I'm sure a good chunk of his 'loss' of possession is putting in crosses which is a tactic for him to do put in many of, and hence incomparable to CM/AM losing the ball. I don't see the issue here, Bruno is fantastic but he does give the ball away cheaply in a way other great creative/attacking midfield players don't - Ozil, Lampard, Silva, KDB, Messi (okay silly to add him here but anyhoo) etc
KdB stats are from arguably his best season, 2017-18 season. Players who tries to unlock the defenses (especially in a team that's more relied on individuals than clever movements) will give away possession, no one remembers KdB or TAA as players who gives away possession, they are known for how productive they are.
KdB also gives away possession lot of times, now it's better as it's under Pep and they play lot of short passes which improves the passing %. For example, his best season at Wolfsburg where he broke assists record, his pass completion % was 74.5%, his 2015-16 season (before Pep became their manager) his pass completion % was 78.3%.
Since Pep took over it's around 81-83% and that's because they play lot of short passes as part of build up. KdB playing for us would be giving away possession just like Bruno does.
Agreed with Ozil though, he was fantastic player at his peak, with insane stats too. James is also one more player like Ozil, fantastic player with very good stats.
Silva isn't a final third player with lot of risky passes, his output isn't comparable to KdB, Bruno or Ozil.
Also, Bruno's short passes completion is 85%, that's not bad at all.
