Celtic boss Ronny Deila on 'comfortable' Cup tie victory

Celtic manager Ronny Deila says although he's happy with his players discipline and performance during the 4-0 defeat of Hearts in the fourth round of the Scottish Cup at Tynecastle, his side should have scored more goals.

The Norwegian says he's also happy with his first six months in charge of the Scottish Champions adding that the only miss so far has been Champions League qualification.
