Benjamin Nygren added a fourth as Celtic eased into the last eight of the League Cup.

Dundee’s cause was hampered by the loss of captain and striker Simon Murray to a knee injury during the first half of the second-round tie.
League One side Ross County shocked Dunfermline with a 2-1 win to progress to the last eight.
Richard Chin’s late strike secured the victory after Liam Lindsay had put them ahead after the break.

With the match seemingly heading towards an extra 30 minutes, the hosts completed the comeback when Clescenco showed superb composure to dink the ball home after Ayr goalkeeper Harry Stone had spilt a deep cross.
