There hasn't been anything confirmed by Sunderland yet, but Histon manager Dennis Greene seems very confident it's going to happen, and is unlikely to go on record in such a way unless things were confirmed;
I've been speaking to Martin since last year about a friendly. He phoned me up the other day and said he'd finally got a date for me.
I played for him at Wycombe and he always tries to help out whenever he can.
He's bringing a lot of the lads that went on the tour with him. There were some young lads in that, but they're proper players, so hopefully he'll bring a good group with him.
It would suggest then that some of the younger players who missed out in Korea, such as Billy Knott might be in line for a game, while players recovering from injury or playing catch-up such as Phil Bardsley and Matt Kilgallon could use the game to get further match fitness.
It remains to be seen whether or not this will be Sunderland or a "Sunderland XI" but if O'Neill is there, I'd have thought it would be safe to class it as a first team fixture, even if it is only days after a trip to Hartlepool United.
