I doubt the deal offered by Cardiff was the main reason he left. The club seemed to genuinely want him to stay - so assume the offer was similar to Bagan and King in length. The reason Bulut gave was that Mark Harris wanted to play football, not sit on a subs bench or in the stands. At his age and stage of career, that sounds convincing to me. He was never going to be a regular starter for us - or for Blackburn - he probably will be for Oxford.
