Per Goal, Sporting released a detailed economic statement on their website, which included an explanation of why Fernandes stayed:
"It was 'impossible' to retain Bruno Fernandes, but we did it. We prepared for his sale by putting a fair price on him, and we had bids, but the only serious offer was from Tottenham and that was €45 million (£40 million/$50 million) plus another €20m in bonuses for winning the Premier League and the Champions League. Those are difficult objectives, so we chose not to accept.
"Bruno Fernandes proved to be not only a great player but a great professional and captain. The dignity and responsibility that he has always shown is exemplary.
"The day I turned down Tottenham's proposal, I came to the training ground and spoke to him. I told him why I declined the offer and why he would stay here beyond the end of the market, and he understood perfectly."
Fernandes previously told reporters he had a deal in place with the Premier League side:
He also told A Bola (h/t The Independent's Samuel Lovett) he liked the idea of playing in England.
The 24-year-old was one of the most talked-about players of the summer transfer window after a phenomenal 2018-19 campaign.
He scored an incredible 20 goals and added 13 assists from the central midfield position, playing a crucial role in Sporting's third-placed finish in the league.
He's off to a great start this season as well:
Tifo Football took a look at the midfielder:
Their need for such a player was compounded by the uncertainty surrounding the future of Christian Eriksen:
Lo Celso's arrival in north London means Fernandes is now unlikely to join Spurs in the next transfer window, but given his current form, it wouldn't be a surprise if another club was willing to match Sporting's valuation soon.
The midfielder is a fantastic talent who makes a big impact, and such a player could be a popular target in January.
