Mourinho took his first training session at Tottenham on Wednesday
Mourinho spent nearly £400m on 11 players during his two years at Manchester United, but believes he has already inherited a quality squad at Spurs.
“The best gift for me, I don’t need players,” he added. “I am happy with the ones I have.
“I just need more time with them. I know them well from playing against them, but you never know them well enough.”
The 56-year-old takes charge of a Spurs side that are 14th in the Premier League with just three league wins all season.
However, Mourinho, who has won trophies at every club he has managed, is confident the club’s fortunes will soon turn around.
He said: “We cannot win the Premier League this season, but we can win it next season. Not will, but can.”
