David Sullivan Jnr, son of West Ham co-owner David Sullivan, has revealed his father is working on bringing in new signings while in his hospital bed.

Sullivan Jnr tweeted a photo on Tuesday night of his father lying in hospital, with a phone in his hand, after he had undergone heart surgery.

The son of the West Ham co-chairman revealed that the 67-year-old “woke up from [the] operation and is straight back on the phone to sign more players”.

The comment appeared to be only partly tongue-in-cheek as Sullivan senior is the club’s chief transfer and contracts negotiator.

The Hammers have had a busy transfer window and have completed eight senior signings.

Hammers boss Slaven Bilic has been in the hunt for a proven goalscorer all summer, and has been linked with the likes of Carlos Bacca, Mario Gomes, Andre Ayew, Christian Benteke, Michy Batshuayi and Theo Walcott, as well as a sensational east London return for Tevez himself.

West Ham announced the signing of forward Andre Ayew for £20.5million earlier in the summer, but he was injured in their Premier League opener against Chelsea last Monda.

Their problems were compounded last week when it was confirmed Andy Carroll would be out until October after picking up an injury in their Europa League tie against Astra Giurgiu.

They have since been linked with Man City striker Wilfried Bony and Juventus striker Simone Zaza.

Bony joined City for £28million from Swansea in January 2015 but has notched just six Premier League goals in that time and found it difficult to make the starting line-up, where his path has been blocked by Sergio Aguero.

Nevertheless, the 27-year-old Ivory Coast international has Premier League pedigree, scoring 32 goals and supplying 10 assists in 90 matches in the competition.

Sky Italy journalist Gianluca Di Marzio claimed this week on his website that the Hammers are in talks with Juventus to sign Zaza, but it remains to be seen if they will agree on a price.

In other West Ham transfer news, an international winger signs after terms are settled.
