Birmingham City defender Curtis Davies admits he wrote to Chelsea asking trials.

Almost £15m worth of transfers later and Davies still feels he has unfinished business back among the ­Premier League's elite in the FA Cup today.

He said: "I've always been a believer that nobody is going to give you anything.

"Football-wise I had no right writing to some of the clubs I wrote to - Arsenal, Tottenham, Chelsea - but if you don't ask, you don't get. But Luton came back to me and it was probably the best move I ever made."
