Whether the shot was saved or not he should have taken the shot. I'd only complain if he launched it clear over the bar or was extremely wide right... Dele does that enough from close range.
Here's the "chance" again...
If you seriously think, in the below scenario, Sissoko should have shot and not passed (with a defender already flying in to block the shot, and the keeper with the right angle clearly covering the goal)...well...
If there's anything to criticise, it was a bad pass from Son.
