Ex-Canaries keeper David Marshall looks set to face his former team-mates from the subs' bench tomorrow - as Cardiff City stick with a man who doesn't appear to know how to lose.

Tom Heaton took over from Marshall last month after a 2-0 defeat at Ipswich, and Cardiff haven't been beaten since.

In half a dozen appearances they have won five, including Tuesday's impressive 4-0 success at Leeds, to move right on QPR's shoulders at the top of the table.

Heaton has grabbed the chance with both hands and is a certain starter against the Canaries.

'I'm thoroughly enjoying myself – and loving the challenge,' he said.

Marshall – who left Carrow Road for Cardiff eight days after they were relegated in May, 2009 – now faces a fight to regain his place.

'One of us has to miss out,' said Heaton. 'We work well together and we drive each other on.

'I want to get better and will work hard to improve. The potential at Cardiff City is massive. I am ambitious, I want to help this football club earn promotion. Every player here has a chance to play their part in what we hope will be a successful season.'
