Much more opportunity to practise taking the ball and passing it on in training. Probably do that 3 or 4 times max under pressure in a game. it's a skill. Just needs practise. he may not be able to do it. Game time is irrelevant as to learning the drill of taking the ball with one foot and passing it on with the other.
If he doesn't have the skill, last thing Id want is for him to try something out in a real game, and for some forward to make an idiot out of him and put it in the back of the net. he'd be even more ridiculed than he is now.
The other thing that might be an issue is that if he goes to SAFC he is going to still be under massive pressure from media and opposition fans. When a player gets questioned, everyone lays into him. If I were him I'd sacrifice 3 months just to see if he can address the problem, and if he can't there's always January.
I think he'll stay. Once you've been questioned in a high profile way, then public doubt, even self doubt will be there. Better to address it rather than go elsewhere and brush it under the carpet. it will keep coming back
