LONDON, England (AP) — Fernando Torres rediscovered his goalscoring touch yesterday with a double strike that enabled Liverpool to stun leaders Chelsea 2-0 and move into the top half of the Premier League.

Liverpool’s worst start to a season for more than 50 years left the club in the relegation zone last month, but a hat-trick of wins have lifted the 18-time champions to ninth.

After the second loss of their title defence, Chelsea are two points ahead of Manchester United and five ahead of third-placed Arsenal.

The Gunners lost 0-1 to Newcastle yesterday, with Andy Carroll’s header inflicting their third loss of the season.

Manchester City joined Arsenal on 20 points after Mario Balotelli scored twice in a 2-0 victory at West Bromwich Albion that ended his team’s three-match losing streak in all competitions.

A rejuvenated Liverpool have now won three straight league matches and the return to form of Torres indicates that Roy Hodgson’s side should not be returning to the drop zone.

The often injured Spain striker has never regained full fitness since being carried off on a stretcher with a groin strain during the World Cup final against the Netherlands in July.

Before yesterday, Torres had scored just twice this season, but he beat Chelsea goalkeeper Peter Cech after just 11 minutes at Anfield.

Dirk Kuyt, returning after a month’s absence with an ankle injury, chipped a pass from the left over Chelsea captain John Terry and Torres took one touch before firing into the net.

Torres’ second came in the 44th minute. Raul Meirele seized the ball after Ashley Cole lost possession in the middle of the pitch and picked out Torres on the edge of the penalty area.

He then cut inside before curling a shot around Branislav Ivanovic and inside Terry and the far post.

There was also a shock at the Emirates Stadium, with Arsenal beaten for the second time this season by a promoted side as Newcastle emulated West Bromwich Albion’s success in September.

Carroll’s goal came on the stroke of half time, with the English striker rising above goalkeeper Lukasz Fabianski to head Joey Barton’s deep free-kick into the net.

Arsenal had Laurent Koscielny sent off in stoppage time after the defender fouled Nile Ranger on the edge of the penalty area.

City’s win at West Brom eased the pressure on manager Roberto Mancini after the team’s dismal recent form.

Balotelli first netted in the 20th after combining with captain Carlos Tevez, who was back in the team following his two-match injury lay-off.

Six minutes later, the 20-year-old Italian striker fired into the bottom corner of the net from David Silva’s cross.

But Balotelli was dismissed in the 63rd following a tangle with Youssouf Mulumbu, who was himself sent off in the 82nd for fouling Tevez.

On Saturday, Park Ji-sung’s double gave Manchester United a 2-1 victory over Wolverhampton.
