Ruben Dias surprised Manchester City on his first day at the club with an unusual request to introduce him to fans.
The 23-year-old has signed from Benfica for £65.2m in what is a club record transfer for the Blues as they hope to have secured the long-term successor to Vincent Kompany.
Dias flew to Manchester on Monday to complete the deal, and asked in advance for an extra shirt to be made available at his signing - not uncommon given players and their nearest and dearest want to mark the day.
However, when he arrived at the training ground the player asked for the shirt to be used to help raise money for a local charity. Following discussions on how best to do that, it was decided to auction off the shirt to support young people in the area.
"Thank you City fans for making me feel so at home already," said Dias.
"To show what your support means to me I’m working with City in the Community to auction off my first signed shirt to help those who need our support most. Whatever we can raise will be used by @citctweets to support young people here in Manchester. If you can make a bid or want to know more please check my stories and swipe up to the following link.
"Can’t wait to wear this shirt. Let’s get to work."
Dias had already left an impression on club media with pointed references towards playing for the fans in his first interviews, and Pep Guardiola will hope the player can have an immediate effect on his squad as they look to head into the October international break with a win at Leeds.
