Super Eagles captain, John Mikel Obi, was furiously unimpressed following their 2-1 defeat to Argentina on Tuesday night.
Lionel Messi opened scoring for the South American side, before Victor Moses levelled in the second half
However, Marcos Rojo volleyed in a late winner, to send the Albiceleste through.
Mikel Obi however feels Nigeria should have had another penalty, after Rojo seemed to have handled the ball in the area.
“Clear handball, clear penalty. It was open. For me a penalty is a penalty. We’ve seen it again and it’s still a penalty,” the Tianjin TEDA midfielder told reporters in the mixed zone.
