Manchester City set to bid for Arsenal target Declan Rice
City are weighing up a move for the 24-year-old with the club on the verge of seeing their in-form midfielder Gundogan leave for Barcelona.
West Ham have already turned down two offers from Arsenal for the England international with the latest bid in the region of £90m.
The Gunners are expected to make a third bid over the coming days for their number one transfer target who is set to cost over £100m.
Personal terms will be sealed quickly once the clubs agree a fee, but their plans could be thwarted by Pep Guardiola who is looking to bolster his treble-winning squad.
Gundogan is understood to have already agreed terms on a two-year-deal at the Nou Camp and will move once his contract with City expires this summer.
Manchester United are also keen on Rice and are reportedly willing to propose a cash-plus-player deal with the Hammers that involves either Harry Maguire or Scott McTominay moving to the London Stadium.
