Yeah I think at the very least last week and this week are an audition for him. I'm of the opinion that because we picked Amartey over Knoll when both were fit, Knoll is a goner and Amartey has a chance but he has to do ok this week.I think whether he plays this week will be telling.
If we intend to keep him, then he should play. Valuable experience.
If we don't intend to keep him there is no point in playing him.
