Europe's biggest clubs are monitoring Vincent Kompany's situation at Manchester City.The Sun says his fall-out with Roberto Mancini has put Europe's super powers on high alert.

Barcelona, Bayern Munich and Real Madrid are all watching with interest and are likely to make a move at the end of the season, especially if Mancini remains in charge.

Barca tried to sign him last year but Kompany eventually signed a new five-year deal with City.
