Alexis Sanchez is on the brink of a big-money move to Manchester United - but what do we know about Fernando Felicevich, the agent representing the Arsenal forward?
Sanchez, who is out of contract this summer, had seemed in line for a reunion with his former Barcelona boss Pep Guardiola at City until United stepped up their interest.
Alongside Sanchez as he prepares to make his move is Felicevich, who reports say could earn as much as £10m from the transfer. Here are five facts about the agent…
He's the 'king of South America soccer'
That's the phrase used by Forbes, who ranked him as the 35th most powerful sports agent in the world in 2017, after he pulled in $18.5m last year.
He's worked with Sanchez since the player was 15
Felicevich has worked on all of Sanchez's transfer moves, having first met him as a teenager emerging from Cobreloa's youth ranks, arranging his switch to Udinese in 2006, move to Barcelona in 2011 and Arsenal arrival in 2014.
He has 39 players on his books - including some other familiar names
As well as Sanchez, Felicevich has also represented Chile stars Gary Medel and Arturo Vidal, as well as former Argentina ace Pablo Aimar.
He has an unusual background
Felicevich is from Argentina - where he developed a love of rugby - and, after studying in Paris, worked in advertising before moving into the world of football agency.
He follows Manchester United on Twitter…
You may have heard about Felicevich's recent social media move. Time will tell whether his following of Manchester United on Twitter is actually a precursor to Sanchez swapping the Emirates Stadium for Old Trafford or merely a football agent keen to keep up with the goings on at one of the world's biggest clubs.
But one thing is for sure - everyone is now keeping a close eye on this agent's actions as speculation about Sanchez's future heats up.
