Hawks boss Steve King has had a busy few days in the player market, with Omotayo joining from Swiss outfit Wettswil-Bonstetten.
King told his club`s official website: “Gold is a big, strong, powerful, out-and-out No.9 and I feel he can bring something different to the group.
“I have worked with him and he looks like he suits the English game.”
As well as Omotayo, Oseni is also in line to make his debut in Essex at the weekend.
Oseni (pictured), 21, lists his preferred position as a central defender but offers versatility as a midfielder.
He came through the ranks at Manchester City, before a spell in Sweden with Prespa Birlik.
He joins the Hawks after a move to SkyBet League Two side Barnet broke down recently after a change in management, but the Bees’ loss looks to be the Hawks’ gain.
