West Ham United have begun a wholesale clear-out of players and backroom staff under new manager Manuel Pellegrini who plans to significantly overhaul the first-team squad with up to seven new signings this summer.

Pellegrini is bringing in a five-strong backroom staff that has worked him for a number of years including assistant Ruben Cousillas and fitness coach Jose Cabello. The trio worked together at Manchester City and Malaga.

Meanwhile neither Patrice Evra nor James Collins – who has spent 11 years at the club in two spells – will have their contracts renewed while defender Sam Byram is understood to be up for sale. In addition at least two more players are expected to be sold while West Ham will not be signing goalkeeper Joe Hart after his loan spell ended. City will accept less than £5million for the goalkeeper.

Collins, who turns 35 in August, played 214 times for West Ham. Evra, 37, played just five games after being handed a short-term deal by Moyes, and has been released. Byram, 24, has struggled to claim a regular place after joining West Ham from Leeds United and can go.

At the same time, following the departure of David Moyes and his four-strong coaching staff last week, West Ham have also told goalkeeping coach Chris Woods, who survived the sacking of Slaven Bilic, that he is no longer wanted.
