Argentina goalkeeper Oscar Ustari has declared it would be unfair if Lionel Messi was unable to enjoy World Cup success before his career was over.
The Barcelona star has struggled to replicate the same level of success he's enjoyed at club level with his nation, with La Albiceleste often falling just short of silverware.
Messi saw Argentina finish runners-up at the 2014 World Cup and consecutive Copa Americas in 2015 and 2016, leading to him temporarily retiring from international duties.
Swiftly convinced to return, Messi then saw Argentina knocked out at the round of 16 stage at the 2018 World Cup before they had to settle for third place at the 2019 Copa America.
