As his nickname suggested a new sissoko/Matuidi type of midfielder with clumsy ball control but then again Bundesliga is different to serie a.
Sissoko and Matuidi were very different players. Clumsy indeed, tho. Although Sissoko takes the cake here. He was the clumsiest of them all

But Sissoko was a defensive beast. All about tackling and intercepting balls. Matuidi was a much more intelligent player. Too bad stats can be found only about Sissoko's last season in Juve. The motherfucker was making 4.6 tackles and 2.9 interceptions per 90 minutes. Only top form Vidal came close to this. But Sissoko's passing was abysmal. He had below 80% accuracy in short passes. Zakaria has below average defensive stats, but his passing seems fine. 91% success in short passes.
Matuidi was somewhere in between. A hard worker with intelligent movement. Statistically he was average. Not great, but far from bad tackler, and 92% successful passes. I hope this Zakaria is much closer to Matuidi than Sissoko.
