The Brazilian right back limped off the pitch during PSG's victory against Les Herbiers yesterday, raising doubts about his fitness.

One of the world's best right backs may have to wait a bit more before confirming his presence in the 2018 World Cup, as Dani Alves suffered an injury setback yesterday during PSG's win against Les Herbiers in the Coupe de France final.

Alves had to be subbed off in the final moments of the game due to a knee injury. Fears of a serious injury were put to rest by the player's antics after the final whistle, which included him celebrating with his team-mates and jumping around with the trophy. Today, fears of the injury's seriousness arised following a statement by his spokesman.

Alves' spokesman revealed that the player will need at least three weeks to recover from the injury to his right knee, leaving him with only two and a half weeks to get in shape for the World Cup.

What makes matters even more complicated is that Alves could still require surgery to correct the problem, but that decision can only be made after those three weeks.

Despite this setback, Alves is expected to be included in the 2018 World Cup roster that will be announced by coach Tite on Monday. Only time will tell if the former Barcelona and Juventus right back is fit enough to play in Russia with A Canarinha.

Alves' World Cup hopes are in serious jeopardy.
