Kosmos, founded by the former Barcelona defender, and the ITF announced a 25-year, $3 billion partnership in 2018 in a bid to revamp the men's national team tournament.

The ITF said at the time of the deal that it would safeguard the historic Davis Cup and provide an extra $25 million a year for the global development of the sport.

The partnership with the 2010 World Cup winner's company also saw the format of the 123-year-old tournament change to an end-of-season 'World Cup-style' event, a change that proved controversial among players.
