Former Chelsea assistant coach Henk ten Cate is concerned about Daishawn Redan's move to Cobham.
The young striker left Ajax for Chelsea last summer.
Ten Cate told Voetbal International: "A striker of Ajax, Daishawn Redan, went to Chelsea last season, a sixteen-year-old, very talented player, you do not know what happens to such a boy.
"Let him rather play at his club, with his friends on the street.
"If he is good, then they will surely, those professional clubs, will see him."
