Some players keep the number they start their career at a club with, such as Chelsea defender John Terry, who wore the number 26 during his spell at the club. On occasion, players have moved numbers to accommodate a new player; for example, Chelsea midfielder Yossi Benayoun handed new signing Juan Mata the number 10 shirt, and changed to the number 30, which doubles his "lucky" number 15.[16] Upon signing for Everton in 2007, Yakubu refused the prestigious number 9 shirt and asked to be assigned number 22, setting this number as a goal-scoring target for his first season,[17] a feat he ultimately fell one goal short of achieving.
