The 24-year-old midfielder is one of the hottest prospects in Portuguese football and is being linked with a move to the Premier League, with Manchester City and Manchester United reportedly leading the interest.
Sporting Lisbon's captain has scored 32 goals and registered 17 assists in all competitions this season and is the reigning Primeira Liga player of the year.
So what makes him so good - and what would he bring to the Premier League?
Better than Pogba? The next Lampard?
Fernandes has 20 goals and 13 assists in the Primeira Liga this season. That means he is sitting above some big names. It is more, for instance, than Manchester United's Paul Pogba and Tottenham's Christian Eriksen have achieved.
The Portugal international has been involved in 46% of Sporting's 71 goals in the league this season. He has been compared with Frank Lampard, surpassing the Chelsea great's most prolific season in 2009-10.
