Re Griffiths and his footwork skills....it may be correct this opinion from some Cheltenham fans or it could be exaggerated.
Given the amount of talk about the importance of goalkeepers being able to pass etc. which has gone on for 3 or 4 years now, especially since Pep arrived at City and the Joe Hart situation, I'd be astonished if any young keepers with any ambition wouldn't have been working extensively on that part of the game in recent years. As Glen Hoddle sometimes says all you need is a ball and a wall and you can work in isolation at improving your skills.
Surely any keeper on professional terms must have half decent hand eye coordination which should translate to being able to be comfortable with the ball at your feet. In short it shouldn't be impossible for Griffiths to improve on this aspect of his game over the next couple of years. Also, any goalkeeping coach worth his salt should see this as one of the important aspects of a players development in the modern game.
