If you're not scoring you get dropped for someone that will and you wait for your chance again. I wouldn't hesitate in starting Nketiah now and bringing on Mateta if that doesn't work. It's just the way it is.
Yep Nketiah has to start for me now. He's looked lively and sharp with his limited game time.
JP hasn't got a great return with the chances he's had, and a few of his misses wont count as they were flagged off. He really has missed some sitters.
