TURIN, Italy (AP):

Juventus avoided any slip-ups against Celtic, finishing off the Scottish team with a 2-0 win yesterday to seal a spot in the Champions League quarter-finals 5-0 on aggregate.

Holding a 3-0 lead from the away leg, Juventus withstood some early pressure from Celtic before Alessandro Matri essentially clinched the series when he put the Italian side ahead in the 24th minute.

Celtic's best chance came minutes later but Juventus goalkeeper Gianluigi Buffon pulled off a one-handed stop to keep out Kris Commons' deflected effort.

Fabio Quagliarella doubled Juve's lead in the 65th minute by slotting into an empty net from close range after being unselfishly set up by Arturo Vidal.

"Celtic is a great squad, we were very focused, very prepared. We knew that this is a team that if you don't study well, can hurt you," Juventus coach Antonio Conte said. "To have managed to return to the top eight of football after so many years fills us - staff, players and whole club - with pride and enthusiasm."

POSSIBLE DOUBLE

Juventus can start thinking about a possible Champions League and Serie A double, as they lead the Italian league by six points.

In the day's other match, Paris Saint-Germain drew 1-1 against Valencia to qualify for the last eight 3-2 on aggregate.

Juventus extended their unbeaten streak in Europe to 18 matches, having lost just one in their last 30 - including qualifying. The Italian club has not conceded a goal in its last five.

It is the end of an impressive European campaign for Celtic, who memorably beat Barcelona in the group stages as well as winning away at Spartak Moscow.

With the series all but decided already, Juventus rested midfielders Stephan Lichtsteiner and Claudio Marchisio, who were both one booking away from a suspension, while defender Giorgio Chiellini and striker Mirko Vucinic were kept on the bench.
