Tuchel guided Paris Saint-Germain to last season's Champions League final which they lost 1-0 to Bayern Munich. PSG sacked the German in December but he was almost immediately hired by Chelsea and led the Russian-owned club to the second Champions League victory in their history thanks to a single goal from Kai Havertz in Porto.
"You know I was so grateful to arrive a second time (in the final after doing so with PSG last year) but this felt different. I told people before somehow it was," Tuchel told BT Sport. He paid tribute to his "unbelievable" players.
"It was an incredibly tough fight, what a fight. Today they were determined to win this. We wanted to be the stone in their (City's) shoe. I told everyone to step up and to be more brave with the ball. Kai was strong and delivered again. He has great heart."
