Nyarko thought his side put in a lot to prepare for the assignment but were left disappointed by the result.
He knows the task to overturn the deficit will be a Herculean task.
“Football is so intricate that, you can hardly predict the scoreline. I’m absolutely shocked about the defeat but it is possible we can overturn the result in the second leg, even though I must admit that, it’s going to be a tall order,” he said.
“We were really prepared for this game, but there will be the need to go back to the drawing board and correct our mistakes ahead of the second-leg.”
