The two all-time greats have dominated football for the past 15 years, but blockbuster moves in the summer of 2021 have seen their goal totals drop off considerably at club level.
That may not be all their own fault though, with the Portugal and Argentina captains keen to show they've still got it during the most recent round of international fixtures.
The duo registered seven goals between them in just two games, more than England, Spain, Germany, France and Belgium combined in their post-season fixtures.
Both playing on Sunday night, Messi got things started with a ninth minute penalty in a friendly against Estonia, and then couldn't stop scoring.
Four more goals followed in a scintillating five-goal display - in a 5-0 win - from the former Barcelona No.10, whose international career has entered a glorious later summer.
Following a first major tournament victory with a Copa America win over Brazil last July, the seven-time Ballon d'Or winner has since seen his side make easy work of European champions Italy to win the Finalissima at Wembley, and things continue to look up.
A side often plagued by incomplete squads and intense pressure back home, Messi may be playing in the best Argentina team of his career, with a World Cup for once met with excitement and not trepidation.
Long-time rival Ronaldo has similarly had a respite from a disastrous season at Old Trafford, making a goalscoring return to action as Portugal captain.
International football's all-time top scorer extended his record with a brace in a 4-0 UEFA Nations League win over Switzerland, taking his grand total to 117 goals.
Both of the footballing greats have won it all for club and country, with just one exception - neither have lifted the World Cup.
And with many of Europe's top sides struggling for goals, their last chance this winter may be their best yet.
