He's playing great. nobody gets past him and he moves forward at the right moment. derby is kind of boring tough despite the atmosphere.
I recorded it. Could send it to you on WhatsApp/Viber/Messenger but it looks like you made your profile/PM private. It's brilliant. He also celebrated it like it was a goal.

Another assist for Kola, currently in the best form of his career; perhaps motivated to get a big move and contract in the next transfer window.
I think that was his first goal for the club at home as I'm pretty sure that he has scored a few more goals.
