Fred has played for Ukrainian side Shakhtar Donetsk since 2013, when he was bought for an estimated €15million euros from Brazilian club Internacional.
A fledgling career
He has played for both the U21 Brazilian national team, where he managed two games, and for the senior side, where he's now featured in six games.
