I had a game where I started at PSV then moved to Roma after 2 seasons and my first buy was Yaya Sanogo for £16million, he was good at the time and proved to be a bargain.
3 seasons later I got the Barca job, by this time Sanogo had turned into the best striker in the game. Not sure if Roma were bitter but they rufused to sell him. Eventually got him for £120millon.
Think this was on FM 12, wish I still had the screenshots. His record for France was more than a goal a game after 120 odd caps
