Former West Ham United star Trevor Sinclair has called for the club's owners to leave.

The Hammers kicked off the season with defeat at home to Newcastle United on Saturday.

West Ham are the only top-flight club not to bring in a new recruit this summer and the scrutiny on the club's board has increased in recent weeks following the sale of Grady Diangana to West Brom.

And now Sinclair, who made close to 200 appearances for the Hammers in five years at the club, has intensified the pressure on the hierarchy at the London Stadium.

He has criticised the board for not backing Moyes in the transfer market, writing on Twitter: "If you can't or won't back Moyes and invest in players needed then sell. #GSBOUT."

That Tweet on Sunday night followed his thoughts following the defeat by the Magpies on Saturday evening, where he said: 'Great transfer window for Newcastle and this was a must win for West Ham looking at our fixtures, long season ahead unless signings made.

"If #GSB (David Gold, David Sullivan and Karren Brady) haven't got the funds to invest in players why not sell the club to a buyer that has the funds and wants to resurrect our club."

Sinclair then uploaded a picture of himself playing for the Hammers alongside the message: "Some care more than others."
