"Celtic, as has been the case on too many occasions this season, have allowed a slackness to creep into their play in the second half. They looked out of sight when Mikael Lustig scored just after the break. The introduction of Efe Ambrose and a sudden uncertainty in the Celtic defence are not unconnected."

Adam Collin gets his angles right to protect his front post with his legs as Celtic striker Leigh Griffiths spins away from his man to get a shot away.

BBC Sportsound pundit Willie Miller is not impressed by Celtic sub Efe Ambrose...
"He is a bomb scare, he has turned this game on it's head. It's quite incredible the chances he gets."

Leigh Griffiths has scored in the three previous meetings with Aberdeen this season and he's after another one as he flashes a shot wide after a good jinking run from Patrick Roberts.

Suddenly, Jonny Hayes is breaking from the halfway line and Efe Ambrose can't keep up. The Aberdeen winger drives into the box and his shot is stopped at the near post by Craig Gordon, with Hayes only able to knock the loose ball into the side-netting.

Nir Bitton bashes a free-kick into the defensive wall and, soon after, Leigh Griffiths does the same. Celtic players will be queuing up for the next one.

Alasdair Lamont
BBC Sport Scotland at Celtic Park
"Celtic have grabbed the occasion by the scruff of the neck, inspired by the precocious talent of Patrick Roberts. You wonder why Celtic haven't been able to produce this hunger and quality more often this season. However, today's first-half performance has underlined their status as the best team in the country."
HT: Celtic 2-0 Aberdeen
Scott Brown may be resting his hamstrings today but the Celtic skipper is being kept busy. He's out on the pitch again to present the Under-20s with their league trophy. Any future stars among that lot?

Aberdeen have been shaky at the back and overrun in midfield. Can they pick up in the second half?
