A vision was set out to Guimaraes when he joined a club fighting relegation.
Newcastle’s hierarchy at the time said they did not just want to go on to qualify for the Champions League – they ultimately wanted to win it.
Newcastle have twice since sat at Europe’s top table, but they are a long way off from taking that next step.
It was rather telling that Isak pushed hard to move to Liverpool, even after Newcastle secured Champions League football in 2025.
As much as Liverpool were able to offer Isak a huge wage increase, because of far superior revenues, the Swede also wanted to compete to win the biggest trophies.
Guimaraes appears to face a similar dilemma further on in his career following a bruising domestic season for Newcastle, who finished 12th in the Premier League.
Arsenal have yet to make contact with Newcastle, who do not want to lose the Brazilian, but does Guimaraes feel this is potentially the last chance he would have to win a Premier League title or the Champions League if they do come to the table?
As loved as Guimaraes is on Tyneside, does the 28-year-old have the patience to help lead a new era at Newcastle with a young group who will take time to flourish?
Newcastle had previously managed to keep hold of their most important players, but the side who made history by ending a seven-decade wait for a major domestic trophy in 2025 has broken up.
Of the 26 players pictured in a jubilant team photograph after the EFL Cup final win against Liverpool, 11 have left the club.
Some changes were overdue, yet there is also a delicate balance to strike.
Newcastle head coach Eddie Howe touched upon this in one of his final news conferences of last season when he warned “the squad can’t get weaker”.
The squad, as it is now, has clear gaps, but Newcastle are understood to have made progress on a move for exciting Freiburg midfielder Johan Manzambi.
Newcastle have also completed the signings of winger Bazoumana Toure, midfielder Sean Steur and goalkeeper Ewen Jaouen.
Turning to younger players from European clubs is a strategy others have adopted successfully.
Bournemouth, who finished sixth last season, have shown how clubs can recover from the loss of key players with the help of smart recruitment and good coaching.
But experience is needed, too, and Guimaraes is priceless to Newcastle in that regard. Losing him would mean the whole project is called into question.
