Celtic picked up a 2-0 win over AZ Alkmaar in the first leg of the Europa League qualifiers last night.
The Hoops produced a well-organised display to secure the hard-earned win and they will be hoping to book their place in the group stages of the competition with a similar result in the second leg.
There were several impressive displays across the pitch but Ange Postecoglou will be delighted with the showing from his defenders.
Celtic have been vulnerable at the back in recent months but they showed great determination and organisation at the back last night.
