Manchester City have joined the battle for Southampton fullback Luke Shaw.
The Sunday Express says City have big concerns about meeting their home-grown quota next season.
City are interested in Shaw, but will face competition from Chelsea, Manchester United and Real Madrid for the £30m rated England left-back.
Mauricio Pochettino admitted on Friday that Shaw is already good enough to play for any side in the world, but remains adamant he is not for sale this summer.
