Former Manchester United and Chelsea boss Jose Mourinho believes that Tottenham are suffering because of star players who wanted to leave the club.
Spurs have endured a difficult start to the Premier League.
They have five points after four games, which some would consider fortunate.
They escaped with two points from games against Manchester City and Arsenal, despite being dominated for large portions of those contests.
"I think in the last part of last season they knew they had no chance to fight for the title and at the same time they didn't feel big pressure from the likes of Man Utd, Chelsea going ahead of them," Mourinho said on Sky Sports.
"They had fourth position more or less under control and the Champions League became more of the dream, so that maybe took some of the focus [from the Premier League].
"But maybe this season they are not having that chemistry. I don't know if I'm right or not but I always felt that while Spurs weren't buying a lot, they were doing something more important, which was to keep all the good players that they have."
