issued a warning to Argentina’s rivals after scoring all five goals in his side’s friendly win over Estonia.
Messi provided two assists to help South American champions Argentina beat European champions Italy in the Finalissima last week.
The Paris Saint-Germain forward and Barcelona legend produced another superb display against Estonia in Spain, scoring an early penalty and then netting two goals in each half as Argentina sealed a 5-0 win.
Messi overtook former Hungary striker Ferenc Puskas and is now the fourth highest-scorer in men’s international football, behind only Malaysia’s Mokhtar Dahari (89), Iran’s Ali Daei (109) and Portugal’s (117).
It was the first time Messi, 34, had scored five goals in a game for his country, having achieved the feat for Barcelona in a Champions League game in 2012.
Following Argentina’s win, Messi wrote on Instagram: ‘We could not close the season better. We won the Finalissima and today we added more minutes preparing for the World Cup.
‘Thanks again to everyone who came to the field and to those who follow us from a distance. We’re going to rest for a few days and we’ll be back very soon!’
Argentina boss Lionel Scaloni added: ‘I don’t know what else to say about Leo, it’s very difficult. He’s like Rafa Nadal, what more can you say?
‘I’ll let the journalists speak. I have no words left to describe him and, above all, for everything he does. He is unique and it is a pleasure to have him, to coach him… his behaviour and how he works for this shirt.
‘I only have words of thanks for Leo, he is not a legend of Argentina but of world football. The day he does not play anymore, we will miss him.
‘I hope he continues playing and everyone enjoys it, because it is a pleasure to see him play.’
Argentina are in Group C for this year’s World Cup in Qatar alongside Saudi Arabia, Mexico and Poland.
