5 players Arsenal should never have signed

#1 Andre Santos

Another panic buy

When a player gets beaten up by his own fans, it raises serious questions about the challenges faced due to crowd violence in domestic football. But once you turn that to an afterthought, one can't help but ponder how deep the fall from grace had been for the said player.

Santos never demonstrated the competence to play for a European giant like Arsenal, and the subsequent years of his career would go on to prove definitively the gigantic error of judgment Wenger made in signing him. One amongst a number of signings prompted by the early season mauling at the hands of Manchester United, Santos was yet another reminder that when Wenger gets it wrong, he tends to get it horribly, horribly wrong.
