Chelsea boss Jose Mourinho has backed Tottenham to launch a serious title challenge this season.
The Portuguese tactician believes six sides are in with a serious chance of winning the prestigious Premier League trophy - but doesn't know who will finish where.
Mourinho, speaking ahead of his side's clash with Tottenham, said on this season's title race: "Tottenham are a big contender. They bought of players with quality," he said ahead of Chelsea's match againtst Spurs.
"Six teams are competing for the position. Any one of the six teams can be first, any one can be sixth."
Manchester United and Chelsea dominated the division by winning a combined seven Premier League titles before Manchester City's final day title win in 2012.
However Mourinho, who won his first Premier League at Stamford Bridge in 2005, insists this season's race will be wide open.
"In my first time time it was a clear race between Chelsea and Manchester United, two fantastic teams who were probably better than any team this moment," added the 50-year-old.
"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."
Arsenal boss Arsene Wenger also stated in his recent press conference that Liverpool and Tottenham will challenge last season's top four - Manchester United, Manchester City, Chelsea and Arsenal - for the Premier League title.
