Lukas Podolski believes the quality of football on offer in the Premier League is better than in Germany.
The 27-year-old had spent his entire career in the Bundesliga with Cologne and Bayern Munich before moving to Arsenal last summer.
And despite three German sides qualifying for the last 16 of the Champions League, Podolski says English football offers the greater challenge.
“I think it is harder here,” he said. “You have tough games and then you see the league in Germany and there is only one team at the front - Bayern.
It is not about saying ‘Arsenal are back’ because we need more of these games and more of these points
“I think the quality in the German league is very good now, not like five years ago. But I think the Premier League is a little bit better.
“When you look at the league now, we have 15 games to go and we must fight to get back into the top four.”
Podolski was in superb form in Arsenal’s 5-1 victory against West Ham on Wednesday, but he says the team will not get carried away by the performance.
“We must believe in our game,” he said. “We have great players in the team and after the games against Man City and Chelsea, the atmosphere was not so good.
“But we won 5-1 and we look to the next game in the FA Cup on Saturday. It was one game and we have three points, which is important, but we have 15 games more to play.
“It is not about saying ‘Arsenal are back’ because we need more of these games and more of these points. Then I think we [will get] back into the top four.”
Podolski has been stationed on the left flank since his arrival at Emirates Stadium, and he says he is comfortable playing either there or up front.
“I played on the left for Cologne sometimes and also for the national team,” he said. “It is not something special. When I play as a No 10 or a striker, I am in the position to score more goals and I can shoot more.
“But with the style of game at Arsenal, I do well on the left side and I am happy to play there. I have scored seven [league] goals now and have nine assists. It’s OK but it’s [more] important for me to be in the Champions League at the end of the season.”Copyright 2015 The Arsenal Football Club plc.
