Alexis admits that he feels “guilty” when he does not score.

The Chile international’s north London derby equaliser was his first Premier League goal since October as he returns to top form.

"I go home, can't sleep and I just think I have to play better" Alexis

Alexis says he is enjoying his time at the club, but feels a responsibility to score or create for his team-mates.

“I think that I've adapted really well in terms of fitting into the club and it's been very good,” he said. “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.”
