Lionel Messi, one of the greatest football players of all time, has stunned Barcelona by telling the club he wants to leave.
The Argentina superstar has spent his entire career at the Catalan giants, but now looks likely to start the 2020-21 campaign with a new club.
Where Messi goes remains to be seen but any deal for the 33-year-old will rank as one of the most dramatic in the history of sport.
Here, we look at a selection of other sporting deals that shocked the world.
Neymar: Barcelona to Paris Saint-Germain, 2017
The Brazilian had formed a potent attacking trio with Messi and Luis Suarez at Camp Nou but a move to PSG was inevitable when the French side met his world-record buyout clause of €222million. He has played an important role in their continued dominance of domestic football, but has so far been unable to guide them to Champions League glory. He was reduced to tears by his side s 1-0 defeat to Bayern Munich in the 2020 final last week.
Paris Saint-Germain is very happy to announce the arrival of Neymar Jr
