London: Salomon Kalou’s second-half double against Middlesbrough moved Chelsea up to second in the Premier League on Wednesday after Liverpool stuttered again by conceding a late equaliser to draw 1-1 at Wigan Athletic.

Liverpool wasted the chance to go level on points with leaders Manchester United after on-loan Egyptian striker Mido converted an 83rd-minute penalty on his debut to earn Wigan a point at the JJB Stadium.

Ivory Coast striker Kalou struck after 58 and 81 minutes to increase Middlesbrough’s relegation worries at a rain-lashed Stamford Bridge.

Chelsea have 48 points from 23 matches, two behind United who thrashed bottom side West Bromwich Albion 5-0 on Tuesday and have played one game fewer than their pursuers.

Liverpool also have 48 points but Rafael Benitez’s side have drawn three successive matches and have picked up 11 points from a possible 21 over their last seven matches.

Spain striker Fernando Torres hit the inside of the post with a glancing header early on at Wigan but Liverpool were rewarded for their first-half dominance four minutes before the break when Israeli Yossi Benayoun latched on to a Javier Mascherano pass to score from a tight angle.

But one goal was not enough to claim three points as Mido, who moved from Middlesbrough last week, scored from the spot after Lucas had brought down Jason Koumas.

The introduction of striker Didier Drogba, again only handed a place on the bench by manager Luiz Felipe Scolari, at the start of the second half provided Chelsea with the attacking impetus to breakdown a resilient Middlesbrough.

Drogba forced Chris Riggott into a rash challenge that earned the defender a booking and soon after the London side broke the deadlock when a corner was only half cleared and Kalou lashed in.

Chelsea’s second also came from a corner with an unmarked Kalou steering in Frank Lampard’s cross.

Fifth-placed Arsenal’s fading title hopes suffered another blow despite Robin van Persie rescuing a point with a last-gasp equaliser in a 1-1 draw at Goodison Park against sixth-placed Everton.

Britain’s most expensive footballer Robinho, arrested earlier this week over allegations of serious sexual assault, played his part in Manchester City’s 2-1 win over Newcastle.
