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.
It seemed not so long ago Manchester United gave 70 million euros for Marcial and offered a 5-year contract, because at that time Marcial was a great hope, but now as you rightly pointed out in his 28 years he is not needed by anyone in Europe.
It is strange that he was offered to play in Brazil considering that Marcial is a rather “fragile” player who gets injured, and the Brazilian championship will not feel sorry for him and although Flamenco most likely wants to sign him instead of Pedro Abreu, who suffered a cruciate ligament injury and is out for the rest of the season, but it may happen that Marcial will be on the injured list with him, considering what a “fragile” player he is. At that time Martial came to Manchester United, he was an hot prospect everyone wanted him, sadly injury woes slowly kill the young lad, I remember when he was trending among new headlines before the transfer.
While Flamengo may look backward, showing is career is coming to an end I believe there's hope for him to do well and attract the eyes of European clubs again, remember Willian was still able to secure a move back to EPL even when he went back to Corinthians, which look as if his career was coming to an end at that time but still keep to Fulham and have a decent stat for his age.
I think the reason Flamengo did go for him was also from the fact that he is quite popular and that will definitely shift the media attention more to them after his signing. Though I hope he can do well and get his career back on track.
