The Portuguese manager endured a troublesome time at Stamford Bridge, which ended in him being sacked prematurely by owner Roman Abramovich.
After a tough start to the campaign with Spurs he has now settled in and the north London side look to be heading in the right direction, sitting fourth in the league and through to the knockout stages of the Europa League.
The 35-year-old admits that he was lucky to get such a high-profile job so soon after his departure from Chelsea.
"Obviously, when I departed from Chelsea it was a difficult time for me. The reasons have been explained lots of times, I don't have to go through them again," he said.
"A possibility to come back to the Premier League was important to me, to stay at this level in a club with a wonderful tradition.
"We are within our objectives. We have qualified for the Europa League knockout stages and we are able to keep this level of form up in the rest of the Premier League."
