Jose Mourinho says Tottenham are title contenders this season ahead of his Chelsea side's visit to White Hart Lane tomorrow.
Spurs are currently joint-top of the Premier League alongside rivals Arsenal, with Chelsea two points back in fourth place.
Despite losing Gareth Bale to Real Madrid over the summer, Spurs invested heavily in their squad by signing seven new players worth more than £100 million, and Mourinho believes they now have the strength in depth to challenge for honours.
"Tottenham are a big contender. They have bought players with quality," he said ahead of Saturday's trip to Spurs," said Mourinho.
"Six teams are competing for the position. Any one of the six teams can be first, any one can be sixth."
Mourinho began his second spell in charge at Stamford Bridge over the summer, but has found it hard to replicate the success of his first spell already.
Three defeats on the bounce consigned Chelsea to their worst start to a season since Roman Abramovich took over at Stamford Bridge.
"In my first time it was a clear race between Chelsea and Manchester United, two fantastic teams who were probably better than any team at this moment," he said.
"Finally, Man City broke that period of blue and red dominance. At the moment the situation is different.
"At this moment six teams are competing for the position, that is the beauty of the league. It is better like this."
Meanwhile, Mourinho has refused to discuss his relationship with Andre Villas-Boas ahead of their first meeting as rival managers since their days together at Inter Milan.
"I don't discuss this with the media, it's a personal thing," he said earlier today. "I don't care what he says. I'm not here to do that. I'm not interested."
