Sunderland boss Roy Keane is wary of Premiership rivals chasing his top Academy prospects.

He said: "Every youth team would have one or two good players so you would look at them, you have to do everything above board.

"You also have to watch who's coming to watch our youth team because we've had people coming to watch our game who shouldn't have been there - scouts from other clubs. We have produced some good players and our youth team was very good last year. A lot are making their mark in our reserves and people are sniffing around them."
