As Atleti were beating Huesca to move three points clear at the top of LaLiga, Barca released a statement prior to their own contest at Camp Nou, reiterating a commitment to the seemingly failed European Super League project.
While that topic seems set to rumble on, Messi served up a reminder of just what the game is at its very best with another sublime showing, scoring twice in an action-packed first half which also saw Sofian Chakla and Clement Lenglet turn into their own nets.
Enes Unal's penalty after a VAR review gave Getafe hope, but Ronald Araujo headed in from Messi's superb corner before Antoine Griezmann converted from the spot in stoppage time.
A magnificent Messi strike seemed set to put Barca ahead within three minutes, yet Getafe survived – the ball bouncing down and away off the underside of the crossbar.
Messi would not be denied again five minutes later, as he beat Getafe's offside trap and finished over David Soria.

But with Oscar Mingueza off the field receiving treatment for a knee injury, Barca were swiftly pegged back when Angel Rodriguez's wayward shot diverted in off Lenglet.
It was a huge stroke of misfortune that saw Getafe concede for a second time.
Soria rushed out to get onto a loose ball, only for Chakla to instead play a blind pass beyond his goalkeeper, whose despairing dive into the net only added to the comedy of errors.
It was 3-1 five minutes later – Messi's right-footed volley coming back off the post, but Barca's talisman was on hand to tuck in the rebound.
Getafe received a lifeline when Araujo was adjudged after a VAR check to have fouled Unal, who converted the resulting penalty to reduce the deficit with 21 minutes remaining.
Yet Araujo made amends in the 87th minute, powerfully heading home from Messi's corner to secure the points, with Griezmann's last-minute penalty adding further gloss to a win which moves Barca third, five points behind Atleti with a game in hand.
