Alexandre Lacazette: At Arsenal 'I have moved into another world'

Alexandre Lacazette says he has entered "another world" since joining Arsenal and wants to adapt quickly and repay the club's faith in him.

Lacazette scored in his first home start for the Gunners on Sunday, a 2-1 Emirates Cup defeat against Sevilla.

In all, he has totalled two goals in six preseason appearances and told French reporters that he's still getting adjusted to his new surroundings.

"It's very different to Lyon, so it's up to me to adapt as quickly as possible and repay the faith shown in me," he said.

"I really have the impression I have moved into another world, be it in terms of the players, the technical staff, the football, everything is different. That's what I came here for. I have to adapt and do that as quickly as possible."

Lacazette was a prolific scorer at Lyon, scoring more than 20 league goals in each of the last three seasons in France. He'll face expectations of a similar haul at Arsenal -- although he acknowledged that the Premier League will be a much tougher challenge.

"It's a great league, lots of teams. I don't think there are any small teams because even against the smallest clubs it's difficult. I'm looking forward to seeing how it goes this season," he said.

"I think I had done everything [in France]. I was happy to finish on a high at Lyon. Now, it's up to me to write my story here."

Lacazette became Arsenal's record signing after joining in a deal that could be worth up to £52 million, and will face pressure to produce right away when the season begins.

However, manager Arsene Wenger said after the loss to Sevilla that Lacazette could need some time to hit his stride.

"It's very difficult, because sometimes it takes a few months, sometimes very little time," Wenger said.

"The only thing I must say with Lacazette, week after week he looks to adapt quickly but overall I think it will take him one or two months."
