The highly rated 18 year old became Wycombe's youngest player when he made his debut two years ago aged 16.
Last year Fulham made a bid for the player.
His potential move to Cardiff was revealed in a Twitter posting yesterday that said
So happy & proud for Kadeem, has his medical tomorrow for Cardiff City. Onwards & upwards!
That tweet and subsequently the account that posted it was removed soon after but by then the word was out.
