Jadon Sancho says he wants to "bring excitement" to Stamford Bridge and emulate his Chelsea idols after his loan move from Manchester United was confirmed.
England international Sancho, 24, joined the Blues until the end of the season in a deal that sees Chelsea pay the majority, but not all, of his wages.
It also includes an obligation to sign the forward for between £20-25m next summer.
His move went through in the early hours of Saturday – the day after transfer deadline day – and was announced by both clubs later in the day.
