Chelsea boss Carlo Ancelotti has cranked up the pressure on Manchester United and Arsenal by insisting neither of them could afford to make another mistake this season.
In what some might construe as the beginning of the managerial mind games for the Barclays Premier League run-in, Ancelotti reiterated his own side needed to win their nine remaining matches to stand any chance of completing one of the great title comebacks.
But the Italian also claimed any further mistakes by United and Arsenal would see the top two pay the ultimate price and miss out on the championship.
"To make a mistake now is very dangerous," said Ancelotti, whose side will take to the field at Stoke looking to pounce on any United slip-up at West Ham. "Make a mistake here you can lose your possibility to win something.
"It's not just for us. Also Manchester United, also Arsenal. They cannot make a mistake either."
