Alexandre Pato had the world at his feet as a 20-year-old.
The Brazilian was a regular in the AC Milan line-up and had scored 18 goals for the Italian giants in the 2008/09 season, including a brace at the Bernabeu during a 3-2 win against Real Madrid.
But, as he grew older, Pato suffered a series of injures and he eventually left San Siro as a 23-year-old.

He finished his six campaigns in Italy, having scored 63 goals in 150 appearances.
Pato returned to his native country in the attempt to rekindle the form from his tender years turning out for Corinthians and Sao Paulo and enjoying a decent goalscoring record - albeit in a much weaker league.
Given his brilliant reputation as a teenager, there was always going to be interest from a major European club later in his career.
Unfortunately for Chelsea fans, that club was yours.
The Blues decided that Pato worth worth a gamble in the January transfer window and signed the 26-year-old on loan until the end of the season.
Chelsea needed back-up to their striker Diego Costa and the club identified Pato as the ideal option.
It hasn’t quite worked out like that.
The striker is yet to make an appearance for the side and couldn’t help as he sat and watched his team knocked out of the Champions League and the FA Cup last week.
It means that Pato has nine Premier League matches to make an appearance for Chelsea, with the Blues having very little to play for for the remainder of the campaign.
It’s understood that he is yet to make his debut for the west London club due to his poor physique and fitness levels.
To make things worse, The Sun are reporting that Chelsea have been paying the player £30,000-per-week.
That means Roman Abramovich has shelled out a staggering £200,000 for Pato to sit and watch his teammates in the stands.
After learning this, Chelsea fans are understandably furious on Twitter. Check out some of the reaction:
Pato may now get an opportunity at Chelsea with the extended suspension hanging over Costa.
Costa was sent-off for two yellow cards during their 2-0 loss to Everton on Sunday and was charged for improper conduct for his behaviour following his dismissal.
That means, if found guilty, Costa could face a three-match ban, giving Pato the ideal opportunity to replace him.
It’s just another example a transfer disaster for Chelsea.
They have signed countless players that have failed to make an impact at Stamford Bridge such as Papy Djilobodji and Radamel Falcao but have also sold players that have gone onto become world-class such as Kevin de Bruyne and the striker had scored twice to knock them out of the FA Cup, Romelu Lukaku.
