Tottenham boss Mauricio Pochettino is worried about Dele Alli's entourage.
Pochettino has made the claim in his new book Brave New World, a diary of last season at White Hart Lane.
He wrote: "The danger remains, as is often the case, that he will forget what has got him to this point.
"I have had to repeat to him this season (2016-17). The other risk is whether those around him know how to treat a top-level professional.
"His WhatsApp photo of a cartoon of a boy surrounded by people who all want a piece of him suggests that he needs to be surrounded by the right people."
