But Messi believes the enforced layoff has had a positive effect on the striker, who turns 30 on Sunday.
Messi will lead the Argentina national side at the 2018 FIFA World Cup in Russian Federation next summer with the Albiceleste looking to go one better than they did in 2014 when they lost in the final to Germany.
"I have come to understand that the season is long and that some periods are more important than others", he explained during an interview with TyC Sports.
Argentina captain, Lionel Messi, has sensationally declared that he and his Argentina teammates will "have to disappear" if they fail to take their last chance of winning the 2018 World Cup in Russian Federation.
Jorge Sampaoli's side nearly did not qualify for the tournament, but a Messi hat-trick in their final qualifier against Ecuador secured their spot in Russian Federation.
"It has very good players, very fast, that if you leave spaces they take advantage of it, but they also let you play and they leave you spaces".
Argentina, who reached the final in 2014, struggled during qualification for Russian Federation, going through three coaches before securing their place at the tournament.
"I'd have to watch them again to see what we didn't get right in order not to win them".
Messi himself has also been left out of the team in recent weeks.
"The bitterness we feel is because we know what's coming if things don't go well for us".
