It wasn’t a vintage performance from Manchester United at Old Trafford against Rostov, but fortunately Jose Mourinho provided some entertainment when he peeled a banana for defender Marcos Rojo to eat.As if he were a tennis player, who often need the source of potassium during long demanding matches, the Argentine needed a quick boost so he looked to his coach for answers. The peculiar episode notwithstanding, the Red Devils emerged victrious with Juan Mata scoring the lone goal on the night.
