Lacina Traore chose a loan move to Everton over West Ham because he prefers the Toffees' style of play.
The Hammers appeared to be the favourites to sign the 23-year old after they applied for a work permit on his behalf.
However, the 6ft 8in Ivory Coast forward opted to join Roberto Martinez's side on loan from Monaco for the remainder of the season.
"The style of Everton suited my technical ability," said Traore.
And Traore said the opportunity to play for a side committed to attacking football was a factor in his decision to move to Goodison Park.
"I looked at the styles of play of the two teams we are talking about and the way in which Everton play is more of a passing side," he added. "It was quite close but Everton was my choice.
Traore only moved to Monaco from Russian side Anzhi Makhachkala at the start of January, but the Ligue 1 club were happy to allow him to go out on loan to get more games.
