Both sides make a change - Emre Can replaces Miralem Pjanic for Juventus. And Roma's Diego Perotti is on for Cengiz Under.

Juventus have the ball in the net but it won't count. A classic case of not being allowed to touch the keeper. A corner is headed into the air and loops its way to Giorgio Chiellini, who beats Robin Olsen in the air to head home. But the whistle goes.

If Chiellini had challenged a defender like that, it would have been 2-0.

Cristiano Ronaldo finds Blaise Matuidi, who tries to wriggle free in the box and his shot is blocked by Kostas Manolas.

Can Cristiano Ronaldo win his personal battle with Robin Olsen?

Cristiano Ronaldo wants a penalty for a Kostas Manolas shove on his back. But the referee gives a free out because Ronaldo handled the ball - he was pushed onto the ball...

Mario Mandzukic really is one of the most hard-working forwards round. Roma have an attack and there is the Croat in his own penalty area to win the ball.

Robin Olsen denies Cristiano Ronaldo AGAIN and this one is the best of the lot. The corner reaches Ronaldo, whose effort from close range is blocked by a great reaction save.

Juve are certain they're getting a free-kick, but the referee says they had their advantage with the Ronaldo shot.

Davide Santon halfheartedly appeals for a penalty as he blasts a cross straight at Mario Mandzukic's gloved hand.

Juve left winger Cristiano Ronaldo is offside as he chases onto a long ball forward.

First chance of the half is to Roma midfielder Nicolo Zaniolo but his 20-yard shot is blocked by Giorgio Chiellini.

The second half = under way.
