London - Chelsea's pursuit of the Premier League trophy will go into May after the runaway leaders drew 0-0 at Arsenal on Sunday with a cautious, ultra-defensive display.
By protecting a 10-point lead over Manchester City and Arsenal, Chelsea can secure its first title in five years by beating Leicester on Wednesday and Crystal Palace next Sunday.
Chelsea was frustrated to have three penalty appeals rejected in the first half at the Emirates Stadium, two involving Oscar and then when Cesc Fabregas was booked for diving.
