They say you should never judge a player on one good international tournament.
In fairness, when Bayern Munich splashed out a reported €35million on an 18-year-old Renato Sanches in 2016, he had already impressed at Benfica, but it was his showings at Euro 2016 for eventual winners Portugal that sped up the hype train.
Just over a year later, he was struggling to get game time during a loan move at Swansea City.
Sanches' star had fallen almost as quickly as it had risen, and after being unable to establish himself at Bayern, the midfielder made the move to Lille in 2019.
At the French side he finally settled and became a crucial part of Christophe Galtier's underdogs, who impressively beat Paris Saint-Germain to the 2020-21 Ligue 1 title.
Sanches followed up his championship medal with another comeback, standing out as one of the best players again at Euro 2020.
As football never seems to learn its lessons, hype rebuilt around Sanches following his performances for Portugal in last year's rescheduled tournament, and the 24-year-old has been linked with a transfer to one of Europe's elite pretty much ever since.
Clubs including Manchester United, Arsenal, Liverpool, Juventus, Barcelona and Real Madrid have all been mooted as possible destinations, but recent reports suggest that Milan could be where Sanches takes the next step of his journey, and potentially where he could finally fulfil that much-discussed potential.
Although Lille have failed to come close to defending their title this season, Sanches has continued to impress when available.
He has played 25 games in all competitions (21 starts), registering one goal and five assists, three more than any other Lille midfielder.
Sanches has completed 57 dribbles, with Jonathan Ikone – more of a forward player and who moved to Fiorentina in January – completing the next most at the club this season (38), and he has created as many big chances (eight) as Ikone having played the same number of games. A big chance is defined by Opta as a situation where a player should reasonably be expected to score.
Comparing the same numbers to Milan's midfield, he has created twice as many big chances as the Rossoneri's most creative players (Sandro Tonali and Alexis Saelemaekers – four), and only Saelemaekers has completed more dribbles (58), albeit from more appearances. Sanches averages more completed dribbles than the Belgian per 90 minutes (3.01 to 2.51).
One assumption would be that Sanches has been earmarked to replace Franck Kessie, who appears likely to be leaving San Siro when his contract expires at the end of the season, though the two are not all that similar as players.
Kessie has six goals this season, two from the penalty spot, but just one assist, and has only created two big chances. Sanches also makes far more dribbles, attempting 91 compared to 38 from Kessie.
Sanches has made almost as many recoveries as the Ivory Coast international (146 to 158) but has attempted fewer tackles than all of Milan's midfielders (20), with the lowest tackle success rate (45 per cent).
His pass success percentage is also worse than Kessie's (81.77 to 88.73). You might think that could be down to the intent of those passes, but Kessie is even more comfortably ahead when it comes to pass success percentage in the opposition half (75.53 to 85.53).
Sanches, of course, plays in a different league, and so how do his numbers compare in this season's Champions League?
While it must be noted that Lille had an easier time of things in the group stages than Milan, who went up against Liverpool, Atletico Madrid and Porto, Sanches did seem to shine on the big stage more than Stefano Pioli's current crop.
Only Ismael Bennacer (39) made more recoveries than Sanches' 38, having played a game more, while no-one at the Serie A side attempted as many as his 209 passes, and none won possession in the opposition's final third more than him (four).
Milan suffered elimination in their group, while Lille won theirs and put up a respectable fight against Chelsea in the first leg of their round-of-16 clash at Stamford Bridge.
Sanches in particular looked good again, though he was unable to prevent the Premier League side taking a 2-0 lead over with them to the Stade Pierre-Mauroy on Wednesday, where Sanches sadly will not play after picking up a muscle injury in the 0-0 draw with Saint-Etienne on Friday.
"Renato Sanches underwent tests this morning following the injury contracted on Friday during the match between LOSC and AS Saint-Etienne," read a statement from Lille. "The midfielder has suffered an injury to the biceps femoris muscle in his left thigh.
"His unavailability is estimated at three weeks, depending on the clinical evolution of his injury."
And this is arguably the thing that has held Sanches back more than anything, his injury record.
For context, at the age of just 24, he already has two pages of injuries listed on his injury history on Transfermarkt, the vast majority of which have been muscle issues that just do not seem to go away.
In terms of what he has shown on the field in the past couple of years, Sanches seems more than ready for another shot at an elite club.
Whether he can stay fit long enough to do so is another matter.
