Alexis Sanchez has revealed that he assumes full responsibility for every game he fails to score in, which gives him sleepless nights. The Chilean has failed to scale his highs from last season this time around and has just broken a two-month stretch without a goal in all competitions after scoring the equaliser against Tottenham at the White Hart Lane.

The 27-year-old has scored seven league goals this season but is far from his clinical best, adding to Arsene Wenger's woes, who is desperate for his team to end a 11-year-long wait without the title. Alexis was on the bench in the Gunners' 4-0 win over Hull City in the fifth round replay of the FA Cup, with Olivier Giroud and Theo Walcott scoring a brace each to get themselves back in the groove.

Arsenal are currently eight points behind Leicester City with nine games left in the season and need to win them to have any chance of challenging for top honours come the end of the season. They are also all but out of the Champions League, with an improbable task of beating Barcelona with a margin of more than two goals at the Nou Camp to ensure progress into the next round.

"I think that I've adapted really well in terms of fitting into the club and it's been very good," Alexis told Arsenal's official website. "But at the same time I'm not the kind of person to become complacent or think, 'That's it'.

"I always want to improve and give my absolute all to the team. The truth is that I do enjoy [the responsibility]. When I don't score goals I feel like I've failed the team and I feel guilty. I go home, can't sleep and I just think I have to play better."
