Barcelona's first-team stars paid tribute to their mothers before Wednesday's win over Villarreal at the Nou Camp.
Lionel Messi and his team-mates each wore the name of their mum above the number on the back of their shirt as they made their way onto the pitch.
Messi wore 'Celia 10' on his jersey, while the back of Philippe Coutinho's shirt read: 'Esmeraldina 14'.
Barcelona also published a 22-man squad list made up entirely of mothers' names.
Mother's Day is celebrated in Spain on the first Sunday in May, but Barca chose to hold the stunt three days later rather than ahead of last weekend's Clasico draw with Real Madrid.
The La Liga champions were given a guard of honour by their Villarreal counterparts ahead of Wednesday's game as a mark of respect following their latest title win.
Barca's players changed into shirts featuring their own names just before kick-off.
Brazilian duo Coutinho and Paulinho got early goals as Barcelona dominated once play got underway.
Messi added a third goal on the stroke of half-time before Nicola Sansone pulled one back.
Ousmane Dembele then got his first brace for the club by scoring twice in the final five minutes.
Dembele's mum, Faty, will surely have been very proud.
