Liverpool’s Luis Suarez sunk his teeth into Chelsea’s top-four hopes with a last-gasp equaliser yesterday but it was his bite on an opponent that overshadowed a day when Tottenham Hotspur virtually ended Manchester City’s Premier League title defence.

Suarez clearly clamped his jaw around the arm of Chelsea defender Branislav Ivanovic during the second half of an action-packed Premier League clash but escaped unpunished.

The controversial Uruguayan’s powerful header six minutes into stoppage time then earned his side a 2-2 draw.

It was a bitter blow for Chelsea, especially as Tottenham had earlier closed the gap in the chase for Champions League qualification with a stunning late comeback to beat City 3-1.

Leading 1-0 through Samir Nasri’s early goal with 15 minutes left, City seemed set to prolong the title race for another week at least but three goals in seven minutes late on from Clint Dempsey, Jermain Defoe and Gareth Bale left them 13 points behind Man. United.

Tottenham’s smash and grab raid meant United can seal a record 20th English title if they beat relegation-threatened Aston Villa at Old Trafford tonight (kick-off: 9pm).

While Liverpool manager Brendan Rodgers said he would need time to view the Suarez incident again and his counterpart, former Anfield boss Rafa Benitez, said he had not seen the bite, the controversial Suarez will again make the headlines for all the wrong reasons.

Suarez, banned last season for racially abusing Manchester United’s Patrice Evra, was never far from the action yesterday, creating Liverpool’s equaliser for Daniel Sturridge with a superb cross and conceding a penalty to allow Eden Hazard to put Chelsea 2-1 ahead.

He then headed in Sturridge’s cross to deny Chelsea who had gone in front before half-time through Oscar.

“It is one point, but when you are winning in the last second, it is incredible to play six minutes and 45 seconds of injury time. You do not see that,” said Benitez who was given a rousing reception by the Liverpool fans.

Earlier at White Hart Lane, Manchester City manager Roberto Mancini was left mystified as to how his side had lost to Tottenham despite looking comfortable for 75 minutes.

Shrugging off the title race as “being over three weeks ago” he told reporters: “For 80 minutes we didn’t concede a chance and we had two or three chances to score, it was all under control. We lost because of two big mistakes.”
