David Gold says West Ham manager Slaven Bilic has the final say on any transfers negotiated by joint owner David Sullivan.

Co-owner Gold shared the transfer policy on his personal Twitter account, as potential transfers loom in the final weeks of August.

The ‘Two Davids’ as they have become known, bought the club in 2010 and have helped the club recover from relegation to become one of the top sides in the Premier League, as well as securing a move to the 60,000 seater Olympic Stadium

They have brought in eight new faces to the first-team squad this summer, including record signing Andre Ayew for £20.5million from Swansea.

Their business is not finished though, as they are now facing a short-term striker crisis.

Ayew was injured on his debut against Chelsea and could be out for four months, while Andy Carroll was injured in their Europa League first-leg against Astra Giurgiu and is out until October.

West Ham are now tracking Wilfried Bony, who is not a part of Pep Guardiola’s plans at Manchester City.

They are also interested in Napoli striker Simone Zaza and they are said to be in talks with the Serie A club over a potential £24million move.
