Championship leaders Norwich City eased to a comfortable victory at Coventry City to extend their lead at the top of the table to four points.
Teemu Pukki put the visitors in front with a composed finish from Emi Buendia's perfectly weighted through-ball and the Finn returned the favour for Buendia to make it 2-0 just before the break.
Callum O'Hare got in behind for the hosts after the break but Canaries goalkeeper Tim Krul raced off his line to deny him.
Victory saw Daniel Farke's men put daylight between themselves and second-placed Brentford, who suffered a surprise 2-1 defeat at QPR.
