Smarting from the recent defeat to arch-rivals East Bengal, Mohun Bagan Super Giant will switch their focus from domestic to international competition as they face an in-form Machhindra FC of Nepal in the AFC Cup in Kolkata on Wednesday. Up against an in-form opponent in the preliminary round two clash, there will be no margin for error for the Juan Ferrando-coached side, which is looking to overcome their its first derby defeat in almost five years. The reigning Indian Super League champions lost 0-1 to traditional foes East Bengal in the Durand Cup three days ago.
