I fucking hate that "chances created" stat. It's one of the most useless stats I hear being thrown around IMO.
Sissoko played nigh on every minute of last season, and especially under McClaren, our tactics were to attack down right hand side through him and Janmaat, so if his "chances created" wouldn't have been the highest in our sorry excuse of a team, it would have been absolutely embarrassing.
Sissoko's poor delivery is part of the reason we got relegated, no matter how many of those are counted as a chance created.
