Marcos Arouca looks like a decent shout. Played in Brazil his whole career so hopefully has less high-profile attention from across the world and affordable wages (last played for mid-table clubs in Brazilian Serie A). 32 y/o DM, 4 caps for Brazil. Very Mandi-like looking at his stats

Couple other names in that position that we could realistically get are Joe Ledley from Derby, John Obi Mikel from Middlesbrough, Evandro from Hull, Almen Abdi from Sheffield Wed
