The son of West Ham United co-owner David Sullivan has expressed his disappointment at the club's decision to sign Arsenal forward Marouane Chamakh.
Chamakh, 28, joined the Hammers on a six-month loan deal last week and Jack Sullivan broke the news on Twitter.
He wrote: "I am very sorry about this news Chamakh has sign a 6 month loan deal! not my pick :("
Sullivan Junior later added: "I hope Chamakh can prove me wrong !?!?!?"
Chamakh has scored eight goals in 40 Premier League appearances for the Gunners.
