The group of people had lined up and were waiting patiently to have their photos taken with Lionel Messi -- but these weren't fans, they were the Argentine's Barcelona teammates.

One by one, members of the squad took it in turns to pose alongside Messi and the Copa del Rey trophy, which Barcelona had just claimed by beating Athletic Bilbao 4-0 in Saturday's final.

Messi, unsurprisingly, stole the show. While this match was perhaps the breakout performance in a Barcelona shirt for youngster Frenkie de Jong -- for the first time truly resembling the star Barcelona bought from Ajax in 2019 -- it was Barcelona's third goal, Messi's first, that this game will be remembered for.

Starting well inside his own half, Messi exchanged passes with Sergiño Dest, before whizzing forward and doing the same with De Jong further up the pitch. 

De Jong's return past found Messi inside the penalty area and the Argentine skipped between two Bilbao defenders and coolly slotted the ball into the bottom corner.
