The Portuguese was sacked last week after just four months in charge of the north London club.
Posting on Instagram, Nuno has spoken out for the first time since his dismissal as he described football as 'the most ruthless in the game'.
He said: "Wow, the last few weeks have been hectic to say the least.
"This is football the most ruthless sport in the game, only a couple of weeks back I was crowned Manager of the Month and fast forward to the present and it's been some days since my dismissal at Spurs.
"This is life, I move on forward now looking for my next challenge and finally I want to thank the fans of Spurs, when I joined this great club I envisaged a vision to bring trophies but all didn't go to plan.
"That's all really we live and learn, look forward to keeping all of you posted and thank you once again for your constant support."
