Liam Delap will wear the No 9 shirt at Chelsea after completing a £30million transfer to Stamford Bridge from Ipswich.
The 22-year-old, who became Enzo Maresca's second signing of the summer after Dario Essugo, will be the 18th man to wear the jersey as the Blues prepare for life back in the Champions League next season.
The two clubs came to an agreement over Delap last week, and after undergoing a medical put pen to paper on a long-term contract in west London on Wednesday.
The Blues have now confirmed that Delap will take on the No 9 jersey, which has proved rather unlucky for a succession of Chelsea strikers over the years.
