Is that our eligibility criteria for captaincy? Shouldn't be the case. De Vrij for example shouldn't be considered.Lautaro is now our longest serving player alongside De Vrij.
What happens when he goes through his routine goal drought and we need to bench him? Captains should be consistent and ever reliable. Not injury prone or mercurial in terms of form. Hakan is the best choice as of now. Possibly DiMarco.Lautaro is a good option imo. There aren't any examples that are more obvious or fitting that Lautaro.
He also leads by example - I can't think of many strikers who work harder for the team. He also doesn't have Barella's annoying tendency of complaining to teammates (Although I love Barella).
