Oulare signed for Stoke City in England in 2002. After his only league game for Stoke against Northampton Town in 2002 Oulare was diagnosed with a life-threatening blood clot in his lungs. He returned for the 2nd leg of the play-offs against Cardiff City and made a vital contribution. He came on after 71 minutes replacing Chris Iwelumo with Stoke 2–1 down, James O'Connor scored in the 88th minute to send the tie into extra time and then in the 115th minute an O'connor free-kick was deflected in off Oulare's backside and Stoke won the tie 3–2 and went on to win promotion. He never got a chance the following season and was released in 2003.
