Manchester City finally look like challenging for the Premier League title under Guardiola after a breathtaking start to the new Premier League season. City currently sit top of the table having won seven of their first eight games. De Bruyne has been central to their rise, scoring a stunner against Chelsea and registering five assists already this campaign. But Spanish website Don Balon claims Guardiola is fearful that the Belgium international could be tempted by a move to Barcelona. It is said Ernesto Valverde’s side have been monitoring the playmaker this season.
