What's more common, a manager taking a skillful player and trying to improve their fitness, or a manager taking a cross country runner and trying to teach them how to kick a ball?
He'll have to drop Fryatt if he does. You could see after that terrible open goal miss that Fryatt had lost confidence in him completely. From then on when he looked up to pass the ball and saw it was McLean he decided to take the shot on instead. That's not going to come back in a hurry.
Neither cross country runner or somebody with skill. Fitness is part and parcel of the modern game. It will be honed as professional progress through the academies into professional footballers. Wenger revolutionised Arsenal when he turned up at the Gooners, by improving fitness. It's now accepted as the norm. Gone are the days when Hull City players would lord it up in Cave Castle chain smoking and knocking back pints like they were going out of fashion the night before a match!!!!
