I'm not too familiar with him indeed, but at any rate I meant it more in terms of career trajectory than as playing style. Still he's also quite small and stocky and from some of the plays I've seen he's explosive with a good first touch and close control. I believe he did have more assists than goals for San Lorenzo, so in that sense he's a lot different from Kun.
He is still very raw.. I think for him to have an impact on Atletico's season we will need to wait 2 or 3 years.. In the games I watched, he just runs very fast in a maze. Piatti (also from San Lorenzo) though, looks like a great player
