The Colombian international’s squad number at Liverpool has been changed from No.23 to the No.7.
Diaz, 26, had worn his last number since his move to the Anfield outfit from Porto in January 2022.
But ahead of the new Premier League campaign, he has now taken the No.7 following James Milner‘s exit from the club.
And the player has offered to replace any supporter’s shirts that have been bought with his old squad number on.
A statement on the Liverpool website confirmed that they would be “personally reimbursed by the attacker”.
It read: “Supporters who have already purchased the 2023-24 replica home jersey printed with the name ‘Luis Diaz’ and the number ’23’ on will be personally reimbursed by the attacker with a like-for-like exchange for a ‘Luis Diaz 7’ shirt.
“The exchange only applies to all ‘Luis Diaz 23’ 2023-24 home shirts or kits purchased in official club retail outlets, via the official LFC online store or LFC Retail app.
“Any qualifying shirts or kit must be returned with proof of purchase by 11.59pm BST on July 31, 2023.
“Any ‘Luis Diaz 23’ shirts and kit exchanged will be retained by the club and donated to LFC Foundation.”

Diaz wore the no.7 at Porto and often has the squad number while on international duty with Columbia.
By wearing the number, he will now follow in the footsteps of club legends such as Kenny Dalglish and Luis Suarez.
Since arriving at Liverpool, Diaz had impressed by scoring four goals and bagging three assists in his first 13 games.
However, he missed a large portion of the last campaign after undergoing surgery on a knee injury that kept him out between October and April this year.
Liverpool currently has the no.8 and no.9 squad numbers unoccupied following the exits for Roberto Firmino and Naby Keita.
