Barcelona are on course to become the world’s highest earning sports club, with record revenues of £804m (€897m) forecast for the financial year 2017/18.

Those revenues are boosted by the sale of Brazilian superstar Neymar to Paris Saint-Germain for a world-record transfer fee of £198m (€222m).

"We're presenting figures for this season which are the highest of any club in the world," Barcelona CEO Oscar Grau said at a news conference on Wednesday.

"No other teams - not even in the NBA or the NFL - reach these numbers. The club is on track to reach its target [of generating €1bn a year] by 2021."

Barca announced revenues of £635m (€708m) for the 2016/17 season (which ended on June 30, 2017) and project a 27 per cent increase for the current campaign.

That would mark a fifth consecutive season of record revenue for the Catalan giants.

For comparison, Manchester United posted revenue of £581.2m (€648.2m) for the year ending 30 June 2017, after becoming the first British club to break the half-billion mark the previous season.
