Will Anthony Martial's career end soon? because he is rumored to be signing a contract with a Brazilian team, Flamengo. Honestly, it was a bad end to his career and after leaving Manchester United, it seems that no European club wants to recruit him. His status is still without a club and that should be used well for any team that wants to bring him in, but on the other hand, the problem of frequent injuries cannot be tolerated and maybe that is one of the reasons that cannot be accepted by any club.
He is still 28 years old and that should be a fairly productive age for a striker, but over the past few years we know he has only spent a lot of time on the bench so it is difficult for him to show his quality. I think Anthony Martial is not as lucky as expected and we can see him very well when he was at Monaco and in his first year at Manchester United.
But the problem is as you said that one of the reasons why Anthony Martial did not get a contract extension at Manchester United was because of his frequent injuries while as I mentioned above that one of the reasons Flamengo recruited Anthony Martial was to overcome Pedro's injury problems, so in conclusion I think there is a possibility that in the end the deal will not change anything for Flamengo because both players have the same problem, but there may be other stronger reasons.
