Even though I know nowt about Stewart, seems a little disappointing if he is the 'surprising' player aforementioned. But, he would fit the profile: seemingly well regarded youngster who'd be in line to be sold in a couple of years for double yer monies. Also, ex Spurs.
Double bonus if we sign Stewart - those who bought a shirt with Stewart (Cameron) on the back can simply dust it off and re-use
He's made 20 first team appearances, but if his Youtube is anything to go by, he needs to be sharper at his passing. Looks like he can take a man on. The start of the video also says his second position is CB, which may be why the move appeals to Leo.
