Manchester City star David Silva has explained his decision to wear number 21 during his time at the club.
The 34-year-old will call time on his City career at the end of the season following 10 trophy-laden years at the Etihad Stadium.
Silva's arrival from Valencia in 2010 marked the start of a new era for the Blues and the Spaniard quickly emerged as one of the finest players to ever grace the Premier League.
Despite having the playmaking ability of a No.10, the midfielder took the vacant 21 shirt following his arrival as Edin Dzeko held the number 10 jersey.
Sergio Aguero would go on to inherit that number and Silva has revealed his choice was no coincidence as he favoured 21 after tricking a teammate during his time with Valencia.
"I moved to Eibar a very short time before the beginning of the 2004-05 season and it was the only one available," he told Man City.
"It was given to me. Then I moved to Celta on loan and 21 was already taken, so I took the number 16.
"Afterwards, I went back to Valencia and 19 and 21 were the only numbers left.
"I was wearing the 21 before and it was also the one of Pablo Aimar at Valencia, a player which, in terms of playing style, was the most similar to me, so I wanted it for myself.
"And here's an anecdote I never told to Jaime Gavilán. That year when both of us arrived there, 19 and 21 were the only squad numbers available, and I got on really well with Curro Torres.
"Me and Gavilán, both newcomers, held a raffle and in a moment when he was distracted, Curro told me which one to pick. It was hidden in his hands and I picked the one with the 21.
"We cheated a little bit there… and Gavi was never aware of that.
"And I've been wearing the 21 shirt until now… and I never told him! I hope he will understand…"
