I think Nwaneri could have been used a bit more over our poorer run, especially when we were persisting with 2 DMs and failing to win. Didn't even need to start. I feel like it shows a bit of urgency to make that kind of sub, and can be the spark that wins it.
Might not, but you can't know unless you try. It transmits something different, to use an Artetaism.
