London, December 17 (Reuters): Alexis Sanchez has said he is very happy at Arsenal but the Chile winger has put the onus on the north London club to put an end to the protracted contract negotiations to keep him at the Emirates Stadium. Arsenal have offered Sanchez, who has 18 months on his current contract, a new deal but fear negotiations could drag on as they are struggling to match the Chilean's 250,000 pounds-a-week wage demands, according to British media reports. "I'm focused more on winning football matches -- I'm staying concentrated on that," Sanchez told Sky Sports. "It really doesn't depend on me -- if they want to show confidence in me. I'm very happy at the club. "It depends on Arsenal. I enjoy the relationship with the fans. I want to achieve more for them. I want to win the Premier League and the Champions League. "I've told my agent I don't want to speak about this too much when all the rumours are going around -- it can distract a player." Sanchez has been in good form this season, scoring 14 goals in 22 appearances so far.
