Tottenham manager Andre Villas-Boas believes the club are still developing their style of play as they continue to make moves in the transfer market.
Spurs have signed seven players already this summer with Friday's acquisitions of Erik Lamela and Vlad Chiriches followed by a deal late in the day for Ajax attacker Christian Eriksen.
But as he looks to take his new-look side into a north London derby against Arsenal on Sunday, the former Porto boss feels his side are at a disadvantage as they are still building their side.
"The advantage that they [Arsenal] have is that they know each other very, very well from the past because they are a side that has been built together for these last years," he said at a press conference.
"Without having new faces, they don't have to worry about building something. They're already in there, the Arsenal way of playing.
"And we have lots of new faces and still have to build our own style of play."
Villas-Boas is looking to continue his side’s 100 per cent record this season following their 8-0 aggregate win over Dinamo Tbilisi in the Europa League on Thursday night, but admitted Sunday’s challenge is a different proposition.
"It is a different type of proposition on Sunday but it has special ingredients of a game that is unique in English football and full of emotion," he contiunued.
"Hopefully, if we set up properly, the match for sure will be a great game, because both teams want to play, want to win, want to attack, and hopefully it can be a present for the fans."
