Dele Alli has joined the same agency that represents Cristiano Ronaldo, Jose Mourinho and Tottenham team-mate Harry Kane.
Alli, 21, has signed a deal with CAA Sports - who also represent Carlo Ancelotti, James Rodriguez and Nico Rosberg - to maximise his commercial value.
'I'm delighted to join CAA at this important time in my career," England midfielder Alli said in a statement released by CAA Sports.
"I'm excited for the future working alongside them.
"It was clear from the start that this is a company that can help me maximise my potential off the field."
CAA Sports, a division of leading entertainment and sports agency Creative Artists Agency, say they will work closely with Alli's manager Harry Hickford "to amplify and enhance Dele's commercial portfolio globally".
"Dele is one of the most exciting players in the world presently, and we are thrilled to have the opportunity to work with him at this pivotal moment in his career, helping to accomplish his personal and professional goals," said Matthew O'Donohoe, of CAA Sports.
