Spurs have enjoyed a bounce since Mourinho took charge in north London, having won three of their four Premier League games and securing Champions League qualification.
“I want to work. I’m going to have time to work, which until now I don’t have.
“I complain every day, the frustrating is I can’t do certain kind of training. It’s frustrating.
“I love pre-season to work. I don’t have. January we’re going to have a little bit and then week in February without Premier League. This is what I want. I want time.”
Spurs have conceded 11 goals since Mourinho took over and have kept just one clean sheet, but he insists January reinforcements are not required in defence.
He added: “No, it is not about the players, it is about the process, it is about the way the team plays, it is about the way the team defends, it is not about the individuals, the player are good players.”
