On-loan Liverpool forward Fabio Borini provided his parent club with a boost ahead of their clash with Norwich City on Sunday by firing the winning goal for Sunderland against Chelsea today.
The Black Cats recovered from an early deficit at Stamford Bridge, with Connor Wickham cancelling out an opener for the second-place home side by Samuel Eto'o midway through the first half.
After stemming a series of Chelsea attacks during the second period, Gus Poyet's team earned a penalty in the final 10 minutes and up stepped Borini to convert from 12 yards and stun the Blues for a 2-1 win.
The teatime result in London leaves Chelsea two points behind the Reds at the summit of the Barclays Premier League, having played a game more, with the two clubs set to meet at Anfield next Sunday.
Brendan Rodgers' team now have the opportunity to open up a five-point advantage in first place when they take on Norwich at Carrow Road on Sunday looking for an 11th consecutive victory.
Borini, who joined the Reds in the summer of 2012 and departed for a season-long loan with Sunderland last September, has now found the target seven times for his temporary club.
