For all that Cannon looks far more likely than Daka to score himself if he gets half a chance, the fact is that with Cannon up front the last few games, as a team we've barely looked like scoring at all. When Daka's there, chances appear all over the place for everyone. I'm not enough of a tactician to explain why this is, but I'm guessing it's because Daka's off the ball movement is way more effective, and/or he's better at putting others through.
