The Tottenham Hotspur midfielder has reportedly decided against appointing a full-time agent.
Alli had previously made the decision to leave long-term representative Rob Segal, but the Daily Mail reports the 21-year-old is now expected to delegate control of his day-to-day affairs to adoptive brother Harry Hickford instead.
The report adds that Alli has also appointed the Sports PR Company - which has looked after the likes of David Beckham, Didier Drogba, Theo Walcott and Petr Cech - to manage his public relations, and Creative Artists Agency (CAA) - whose client list includes Jose Mourinho, Cristiano Ronaldo, James Rodriguez and Harry Kane - to oversee commercial deals.
According to the Daily Mail, however, appointing a new agent is something the Tottenham player could revisit at a later date.
For the time being, though, Alli's future looks to be with Spurs, with the report adding he has "no burning desire" to leave the north London club any time soon.
And it is claimed the news of his new management team will raise hopes of Alli agreeing a new contract, which Spurs are said to be keen to extend - while making the £50,000-a-week star one of their top earners.
