Manchester United and bitter rivals Manchester City are involved in a transfer war over Rochdale teenage wonder Luke Matheson. 

The England U-18 defender, who made his league debut at just 15, is attracting a stream of interest from across the Premier League.

The list of top-flight scouts checking up on Matheson gets longer by the week – and League One Rochdale fear they will not be able to keep hold of the right-back beyond the January window.
