Spain international Diego Costa says his decision to leave new Spanish champions Atletico Madrid for English football was motivated by a desire to play for "one of the greatest clubs in the world".
According to reports, Chelsea have agreed to meet the centre forward's release clause and struck personal terms that will make him one of their best-paid players - with Costa having passed the medical exam.
And the Brazilian born striker has claimed that his desire is to play for one of the greatest clubs in the world.
"Why would I have chosen to play for Chelsea? It is a thing that is about to happen," Costa told Goal.
"Things are going in a direction and, if they keep going as they are going, it is the team I will play for in the next season.
"I've wanted to play in the Premier League for a while. Chelsea are one of the greatest clubs of the world so there are many factors that make you take a decision like this."
