10 Hardest Men Who Ever Played For Celtic

A towering centre-back, Bobo Balde spent eight years at Parkhead after joining Martin O'Neill's side in 2001. The height of his career was also its biggest low - when he saw red in the UEFA Cup final with Jose Mourinho's Porto two years later, with his side going on to suffer an extra time loss. But did he cry about it? We don't know, honestly.

But probably not. The Guinean became one of Scottish football's most commanding defenders almost immediately after his arrival from Marseille. He was never the kind to stamp his feet around or butt heads with opposing players - but he didn't need to. He was simply a colossal footballer against whom few would be unwise enough to raise a hand.
