“At this level you’ve got to maintain it throughout the whole season. “We’ve done well in the past but then our form’s dipped in the New Year, maybe towards the end of the season, so it’s just about doing it as much as possible over the Christmas break and then into the New Year and we’ll see where it takes us. “Obviously Chelsea are not playing very well at the moment but I wouldn’t write them off. They were champions last year for a reason. “Again, we’ve just got to concentrate on ourselves, try not to think about the teams around us. We’re playing very well, we’re got great belief and we’ve just got to keep trying to move up that table.” Press Association Harry Kane feels Tottenham’s unbeaten Barclays Premier League run proves they can compete at the top end of the table. The England striker scored his sixth goal in four matches to give Spurs the lead in Sunday’s north London derby, only to see hosts Arsenal snatch a point through substitute Kieran Gibbs. The 1-1 draw moved Mauricio Pochettino’s side up to fifth in the standings and just five points off the summit, having not lost in the league since their opening-day defeat at Manchester United. “It shows that we can be up there with the big teams,” Kane, who will now link up with England, said of the unbeaten run. “We probably deserved to win against Liverpool, we beat Manchester City and probably maybe deserved to win at Arsenal as well. “We’re not just drawing where we’re hanging on, we’re drawing where we’re playing very well and there are chances we could be winning these games. “We’ve just got to keep doing what we’re doing – there’s a lot of games still left to play. We’re now into the international break and when we come back it’s two more London derbies.” Those derbies come against in-form West Ham and beleaguered Premier League champions Chelsea, with the Blues’ poor start to their title defence offering the chance for a different side to challenge for a top-four finish. Jose Mourinho’s side are down in 16th place having lost seven of their first 12 matches and, although he refused to put Tottenham in the title picture, Kane knows they are good enough to be in and around the business end of the table. “There’s still a long way to go and we’re not going to come out and say ‘we’re title contenders’ but we’ve just got to keep doing what we’re doing,” he said. “We’re in a great position at the moment, we’ve played a lot of tough teams but there’s still a long way to go.
