West Ham are set to enter a new era following the appointment of Manuel Pellegrini on a three-year deal at the London Stadium.

The former Manchester City boss has plenty of work ahead of him this summer to rebuild his side and has reportedly decided on his first addition, bringing in someone to join the backroom staff.

The Daily Express states Pellegrini will bring in Ruben Cousillas as his assistant with the Hammers, reuniting with a loyal colleague from his experienced career.

Pellegrini has worked alongside Cousillas at River Plate, Villarreal, Real Madrid and Malaga – and the pair are set to join together again at the London Stadium.

Cousillas will join as Pellegrini’s first appointment to the backroom team and others are likely to follow in the coming weeks, while the club will also focus their attention on the transfer market.

The Hammers are reportedly eyeing a new central defender, central midfielder, striker and goalkeeper in the summer window to improve their ranks.
