Campbell can be key to promotion, says Mackay

Cardiff manager Malky Mackay claims Fraizer Campbell's double in the 2-1 win over Bristol City shows the former Sunderland striker is the final piece in his club's promotion jigsaw.

Mackay's side is now eight points clear at the top of the Championship after Campbell (pictured), an ex-Manchester United trainee, marked his full debut by killing off struggling City on Saturday.

Campbell, signed from Sunderland during the January transfer window, opened the scoring on the stroke of halftime when he ran onto Tommy Smith's clever through ball and slotted past goalkeeper Tom Heaton.
