Celtic manager Brendan Rodgers admitted they need to sort out their pitch and their penalties following a narrow victory over Ross County.

Rodgers claimed the Celtic Park surface was more like a field than a pitch after his side laboured at times towards a 1-0 win which restored their five-point lead over Rangers in the cinch Premiership.
