Written off by all and sundry as the most expensive flop in English Premier League history, Fernando Torres is seemingly back in business.

Four goals in two games have transformed the misfiring striker from the on-pitch personification of Chelsea's recent problems to perhaps the man who can earn Rafael Benitez a bit more time in the club's managerial hotseat.

"I said before that if the team play well and create chances he will score goals," Benitez said after Torres netted twice in Saturday's 3-1 win at Sunderland -- Chelsea's first victory in eight EPL games.

"It's fair to say that we are watching a Torres with more confidence and belief. I was analyzing his movements and adjusting a few things. It's a question of confidence and differences in movements. The most important thing is that he appears confident."

The victory kept Chelsea third ahead of Sunday's Manchester derby -- seven points behind leaders United and four adrift of second-placed City.

It capped a week which started with Chelsea's embarrassing group-stage exit from the Champions League and which will end with the squad traveling to Japan for the Club World Cup.

Torres ended his two-month drought with two goals in Wednesday's 6-1 thrashing of Danish team Nordsjaelland, but the next day he had an immediate reminder of his earlier struggles from the man he is seeking to follow as a Chelsea hero.

Didier Drogba, back training with the club to keep fit for next month's Africa Cup of Nations, put on a lavish dinner for last season's Champions League-winning team -- spending a reported $1.3 million as he had special commemorative rings made for his former colleagues.

Torres did not attend the affair laid on by the player who kept him out of the Chelsea starting lineup following his $80 million move from Liverpool -- Drogba, the fan favorite who finally delivered the European title that owner Roman Abramovich has always craved, with his last kick for the club before moving to China.

Whether it served as a catalyst for Saturday's performance, only Torres knows, but the Spain international shrugged off the lethargy that followed his promising start to this season as he looked more like the man who starred for Benitez at Liverpool.

Torres opened the scoring in the 11th minute from Eden Hazard's cross for his first in the EPL since October 6, and made it 2-0 at halftime with his first successful penalty in English football after Sebastian Larsson tripped Ramires.

Torres hit the crossbar soon after the break, but compatriot Juan Mata followed up to score, and Sunderland dropped into the relegation zone despite a consolation from Adam Johnson.

It was Benitez's first league win in four games since replacing the sacked Roberto Di Matteo, a hugely unpopular appointment with the Chelsea fans.

"Little by little we are adjusting things, but if we have more confidence, with the quality we have we will win games," said the Spanish coach, who will now seek to repeat his 2010 Club World Cup success with Inter Milan -- after which he was promptly sacked having fallen out with players and officials at the Italian club.

"It's important to have an opportunity to win any trophy, but especially this one," Benitez said.

"It was a great experience for me and I hope it will be for my players. I got to the final in 2005 and won the tournament in 2010."

Arsenal ended a four-match winless run by beating fifth-placed West Brom 2-0 thanks to two penalties from Mikel Arteta -- the first coming after an apparent dive from fellow Spanish midfielder Santi Cazorla.

"There was zero contact, it wasn't even close. I am not sure what the referee saw," West Brom manager Steve Clarke said.

"It was a bad decision for us and obviously changed the shape of the afternoon. We knew the longer the game went the more pressure would come on Arsenal."

Arsene Wenger's team had dropped to 10th after last weekend's defeat by Swansea, but climbed back up to sixth as the London side bounced back from the midweek Champions League loss to Olympiakos.
