Great call, and a RC I would guess too!!!
Just to be controversial, not convinced it was a genuine attempt to play the ball, but looks like the referee on the night thought it was...*yellow card I'm sure that's what you meant though!
Certainly it's desperate but could it still be a genuine attempt? In the circumstances I'd expect the defender to make a challenge and at least he has tried to make a tackle rather than blatantly trip, hold or push his opponent. I'd give the defender the benefit of the doubt and go with a yellow card and penalty.It's clearly a desperate attempt to get the ball, but that's what he's trying to do imo
