Chelsea boss Carlo Ancelotti has set his players a winning target if they're to successfully defend their league title.

Ancelotti reckons his Chelsea side must win 13 of their remaining 16 games if they want to successfully defend their Premier League title.

He knows there is almost no margin for error, as he found out in similar circumstances while captain of Roma 25 years ago.

"In 1986 we needed to close a gap of eight points when it was two points for a win," he said of his side's battle to overhaul Juventus.

"We ran for two months closing the points, eight, seven, six, five.

"The last but one game we were level and we lost 3-2 at home to the bottom team, Lecce.

"Before, there was a celebration in the stadium. The coach of Lecce even said, 'I am a fan of Roma. I hate Juventus'.

"We were not able to win and Juventus won the title. This is life."
