West Ham have rejected Arsenal's first bid for England midfielder Declan Rice.
However, it is understood the initial offer for the 24-year-old has left the Hammers unimpressed as it contains a number of clauses.
Sources at West Ham do expect further communication from Arsenal, although they are also anticipating an offer from Manchester City.
City are refusing to comment on potential interest in Rice.
However, uncertainty remains over the futures of captain Ilkay Gundogan and Bernardo Silva, which could force Pep Guardiola into the transfer market.
