Medel has been a complete disappointment, and I didn't expect much to begin with. I thought he was stronger and faster, instead he loses like half the physical duels and gets outrunned by everyone, his positioning is just awful, it's super irritating how he leaves his position to go on tackles that he never had a chance in hell of winning all the fucking time, his tackling is also pretty average, I would say that everytime he goes for a tackle there's like 50% he'll get the ball, which is mediocre for a DM.
Shockingly his passing and composure on the ball are the only things that have surprised me positively, they're not great, but are OK. His long balls when the opponents give him some time on the ball are pretty nice.
