Celtic have temporarily moved to the top of the Scottish Premier League table with a 2-0 win at Aberdeen.
The Hoops could have taken the lead midway through the first half, but Tony Watt's effort came back off the post.
Aberdeen's best chance of the opening 45 minutes came from Niall McGinn, who fired narrowly wide with a low drive.
The visitors enjoyed much of the play after the break and they eventually made the breakthrough on 74 minutes when substitute Lassad Nouioui converted the rebound after Victor Wanyama had hit the woodwork.
Their advantage was doubled just four minutes later as Charlie Muglrew curled the ball past Jamie Langfield.
