BUENOS AIRES: Less than 24 hours after calling time on his international career, Lionel Messi said on Wednesday he was already missing wearing the Argentina jersey.

The eight-time Ballon d'Or winner, who scored a penalty in Tuesday's 3-0 win over Benin in his Buenos Aires swansong, had described the occasion as the "saddest day of my career".

Messi led Argentina to World Cup glory four years ago but his team came under severe criticism for their aggressive style of play during their run to the final in July, when they lost to Spain.

"Yesterday was my last match and I'm already missing the light blue and white jersey," said Messi on social media.
