Is this his first season at senior level? Based on transfermrkt it looks like he only became a starter mid way through the season too. That's a some rise for him.
Don't know anything about him other than YouTube. He looks athletic with a decent touch and seems to take pride in defending which is a good sign. He also seems to make a lot of covering challenges, which maybe suggests his positioning isn't good. But you can't really read too much into highlight videos.
We needed a fullback so hopefully he can make a difference for us.
