The football agent at the heart of negotiations for Declan Rice is Neil Fewings from the Wasserman Media Group.
The 19-year-old defender was previously managed by Playerworks but recently moved agents to Fewings.
Fewings is also the FA listed intermediary involved in transfer deals involving Jack Wilshere, Junior Stanislas, Rob Green, Mo Diame, Victor Moses, Jason Puncheon, Vigil Van Dijk, Tom Huddlestone and Ryan Bertrand.
In March 2017 WHUFC.com announced Rice had signed a new three-and-a-half-year deal with West Ham securing his services until 2020.
That deal was worth £3,000 per week basic wage plus £10,000 bonus per first team appearance.
The teenager made 35 appearances last season earning him £350,000 on top of his £156,000 per annum basic wage.
Claret and Hugh understand that the club have offered a new package £15,000 per week basic with appearance clauses that could take him to £30,000 a week in total.
Pellegrini will get the final say whether that offer will increase but for the time being there is no agreement.
