Chelsea hope to conclude negotiations with Willian over a contract extension in the new year.

The club want to reward the Brazil international for his superb performances this term by securing his long-term future at Stamford Bridge.

While Chelsea have struggled this season, Willian has taken his game to another level and is the club’s top scorer with five goals.

His current deal, worth around £80,000 a week, expires in 2018 but Chelsea want to give him a minimum of another two years and take his pay to £100,000 a week.

Talks have already begun and it is just a matter of time before an agreement is announced. Chelsea have been keen to tie down some of their key players. Eden Hazard signed a new five-year contract in February, while Willian’s Brazil team-mate Ramires also committed himself to the club until 2019 last month.

Chelsea vs Norwich - player ratings 22 show all Chelsea vs Norwich - player ratings 1/22 Asmir Begovic: 6 Easily dealt with the few chances he was faced with as the Canaries’ forwards ultimately failed to give the goalkeeper a busy afternoon. 2015 Getty Images 2/22 Branislav Ivanovic: 6 Looked reinvigorated upon his return to the starting line-up following his recovery from injury and, although he defended well enough, he did allow Brady to get past him a few times as Norwich went on the attack. 2015 Getty Images 3/22 Kurt Zouma: 7 Put in a strong defensive performance on what would have been an emotional return to club football for the France international. He also came close to scoring with his volley in the second half and a lovely flick from Willian’s free-kick that hit the bar. 4/22 John Terry: 6 Blocked Bassong’s shot with five minutes of the first half to play to deny the visitors a potential openerafter earlier seeing his audacious flick go wide of the goal. Was a solid game for the Chelsea skipper but, in truth, he was never really tested by Norwich’s forwards in the game. 5/22 Kenedy: 7 Despite starting in the unusual position of left-back, the Brazilian enjoyed a superb showing in defence as he patrolled his area well and used his pace to regularly help contribute to Chelsea’s attacks.One of his crosses nearly led to a goal; it proved an inspired inclusion in the team. 2015 Getty Images 6/22 Cesc Fabregas: 7 Enjoyed a much more positive game, with the Spaniard setting up Costa’s goal with his quick free-kick, while later forcing Ruddy into a save himself. Generally linked up well with Hazard, Pedro and Willian. 2015 Getty Images 7/22 Nemanja Matic: 7 Was excellent in midfield as he dominated the play from the middle of the park by winning possession and then helping drive Chelsea’s attacks forwards – nearly scoring a wonder goal late on. Suffered one nervy moment when he was outmuscled by Brady, which ended in a chance for the visitors, but Matic will be pleased with his showing 2015 Getty Images 8/22 Pedro: 6 The Spaniard’s pace helped him get past Wisdom to create chances for Chelsea several times in the game, but his impact waned as the game progressed. Still, his link-up play with his team-mates made for a more fluid performance than in previous games. Was replaced by Oscar with seven minutes to go. Julian Finney/Getty Images 9/22 Willian: 6 The Brazilian was another important player going forwards for the Blues, although he did escape giving away a penalty after clattering Brady in the area. 2015 Getty Images 10/22 Eden Hazard: 7 The midfielder impressed from his No.10 role and he proved to be one of Chelsea’s best players, if not the best, on the pitch. The Belgian’s direct play and desire to be the difference resulted in him causing Norwich’s defence several problems throughout the game – indeed he won the free kick from which Costa eventually scored. Showed he has the ability to step up when his team needs him the most. 11/22 Diego Costa: 7 The striker scored the only goal of the match when he calmly drove a low shot past Ruddy in the second half. However, Costa will still feel he should have been more clinical after sending earlier shot over the bar. His tendency to go down too easily in the box – which he did against Norwich when under pressure from Bassong – needs to be addressed. 12/22 John Ruddy: 7 Made several impressive saves in the game – using his foot to keep out Costa’s shot in the 42nd minute and preventing Matic from scoring what would have been a wonder goal late on. However, he couldn’t save Costa’s effort for the winner. 2015 Getty Images 13/22 Andre Wisdom: 5 Found himself a weak link at right-back as Pedro, Willian and Hazard found it all too easy to get past him throughout the game. 2015 Getty Images 14/22 Ryan Bennett: 5 The defender shackled Costa well alongside Bassong, but he will feel he let himself down when he failed to do enough to keep up with the striker for the goal. 15/22 Sebastien Bassong: 7 Was one of Norwich’s best performers at the Bridge as he used his strength to deal with Costa superbly while never being afraid to come out and deal with the numerous threats Chelsea posed. The centre-back should, however, have done better to lift the ball over Terry while in front of goal. 16/22 Martin Olsson: 5 Struggled to keep up with Willian and the interchanging play of Pedro and Hazard. Received a yellow for fouling Costa. 17/22 Nathan Redmond: 5 Had a quiet game from his position just behind Mbokani, and was unable to use his abilities to get past Matic. 18/22 Gary O'Neil: 5 O’Neil had a tricky time dealing with the pace of Hazard, the trickery of Fabregas and the smooth attacking play of Pedro and Willian. 19/22 Youssouf Mulumbu: 4 Endured a difficult afternoon in the middle of the park with Hazard running riot. Was cautioned for pulling back Pedro and was later taken off after Chelsea went ahead. 2015 Getty Images 20/22 Robbie Brady: 6 Had a penalty appeal turned down after coming together with Willian in the box. Had one of Norwich’s best chances to equalise shortly after Costa scored but drove his shot just wide. 21/22 Jonny Howson: 5 Made a superb challenge to dispossess Willian on the edge of penalty box as Chelsea attacked in the first half, but failed to really create any clear-cut chances for the visitors. 22/22 Dieumerci Mbokani: 4 Never created any clear-cut chances to score and largely disappointed before being taken off and replaced by Jerome late on. 1/22 Asmir Begovic: 6 Easily dealt with the few chances he was faced with as the Canaries’ forwards ultimately failed to give the goalkeeper a busy afternoon. 2015 Getty Images 2/22 Branislav Ivanovic: 6 Looked reinvigorated upon his return to the starting line-up following his recovery from injury and, although he defended well enough, he did allow Brady to get past him a few times as Norwich went on the attack. 2015 Getty Images 3/22 Kurt Zouma: 7 Put in a strong defensive performance on what would have been an emotional return to club football for the France international.

Willian was signed by Chelsea from Anzhi Makhachkala for £30million in 2013 and was a regular in the side that claimed the Premier League and Capital One Cup last season. All of the 27-year-old’s goals this season have come from free-kicks.
