But things could have been very different had the Red Devils, who were scouting Isco as a 21-year-old at Malaga, attempted to bring him to Old Trafford.
Towards the end of the Sir Alex Ferguson era at Manchester United, the club were keeping tabs on Isco with a look to making a concrete bid.
A senior scout was sent to Spain to keep an eye on the youngster, and report back on whether or not he would be a good signing for the Red Devils.
According to ESPN, the attacking midfielder was watched on several occasions before the scout decided that Isco wasn’t right for Man United.
Hard to believe considering just how good the Spaniard is, even for Manchester United’s high standards, and even harder to believe upon learning the reason why.
“He’s good, but not quite quick enough and his head is too big for his body,” was the response from the scout, according to the news site.
Isco eventually moved to La Liga giants Real Madrid, where he has continued to grow into a key member of their Champions League winning team.
The Spaniard’s consistency has seen him pose a serious challenge to Gareth Bale for a regularly spot in the first team.
And on Tuesday night he ensured Los Blancos would be taking the Super Cup back to the Spanish capital with them with a quality second-half effort.
As to be expected, news of the scouting report has been mocked on social media, and Jamie Carragher was among those to poke fun at Man United.
Taking aim at his fellow Sky Sports pundit Gary Neville, the Liverpool legend tweeted a link to the story, adding: “Bizarre that considering the success they had with Gary Neville”. Brilliant.
