Juventus coach Massimiliano Allegri has admitted that his team must improve after Tuesday's 1-1 draw with Inter Milan.

The Serie A champions suffered a setback in the defence of their title last night as they were forced to share the spoils at home to Inter.

Carlos Tevez gave the hosts an early lead before Mauro Icardi levelled for the away side midway through the second half.

"It's a shame we weren't able to win our first match of 2015," Allegri told the club's official website. "When we make mistakes we lose our calm.

"We were too static when moving the ball around in the second half, while in the first half the midfielders made themselves difficult to pick up. We must improve and manage to maintain our level of display for the entire game, not just 50 minutes."

Juve continue their Serie A campaign on Sunday when they travel to Napoli.
