The best passes are a massive part of quick play and winning games, I've seen him pass behind a few times.
The better the pass Dele gets, the quicker he can do something with the ball, maybe something was on with a better pass from Gio.
No one but the players know, so why try to apportion some sort of blame behind things that happen between passionate players in the heat of a match all the time?
IMO He's not really siezed his chances when given minutes so far, he needs to put in a good show soon.
