Bamidele Jermaine "Dele" Alli (b. 1996) is an English professional footballer who plays as a midfielder for Premier League club Everton and the England national team. Alli was born in Milton Keynes, Buckinghamshire, to a Yoruba Nigerian father Kehinde and English mother Denise. Kehinde moved to the United States a week after Alli's birth. Alli was initially brought up by his mother, who suffered from alcohol problems. At the age of nine, he moved to Nigeria with his father, where he spent two years in an international school before returning to Milton Keynes to live with his mother. Alli went to Stantonbury Campus and The Radcliffe School in Wolverton.

At the age of 13, he moved into the family home of Alan and Sally Hickford, parents of another young footballer with MK Dons and whom he refers to as his "adoptive parents" although he was never legally adopted by them. In the summer of 2016, Alli elected to stop wearing his surname on his match shirts because he felt no connection with the Alli family name, instead opting for "Dele".
