In case you hadn't noticed, most captains are fiery. After Vinnie, I would say Kev is the most fiery one.
If we are going by moments, didn't Fernandihno try to choke Fabregas? And by your system shouldn't that disqualify him?I disagree that KDB is a front runner. I can't deny how good a footballer he is, but he's had his moments (let me talk!/Getting angry after getting injured v Crystal Palace).
For me it should be David Silva or Fernandinho this year and then Sterling once they move on.
