Arsenal boss Arsene Wenger believes Tottenham will have to reassess their ambitions after yesterday's 3-0 derby defeat.
Spurs boss Harry Redknapp insists there was nothing between the two teams - apart from "two mistakes".
But when asked about the top four becoming a top six, Wenger told arsenal.com: "You have to see on a longer period. I believe that I am very positive because when you look at our performances I feel we have the minimum points with the performances we have produced so far.
"We were unlucky losers at Man United, we were at 1-1 with 15 minutes to go and we looked the more likely to win the game. That's why I believe if we keep our attitude we have a fair chance. Will Tottenham be up there? I don't know yet, it's too early."
