He's one of Adidas' main men. If he wanted a round handle I'm sure they would just custom make one for him instead of him having to recap a stick. Plus the round cap wouldn't fit great over an oval shaved handle I wouldn't have thought. Also in recent photos there's no clear groove on the shaft when compared to the World Cup in 2014. I obviously don't know and wouldn't argue too hard, but I'd guess he uses a TX with DF graphics, I'm happy to be corrected though.
