Because I haven’t scored for quite a long time so today was to prove myself. I had a goal. I was feeling happy for the goal but it is really a big blow for me and my club as well as the Black Stars [to have gotten injured]. I am really sad at the moment,” he said.It is however too soon to determine the seriousness of the injury.Gyan said he is not too sure if could feature in the game against Brazil and needed to undertake a few test to ascertain the seriousness of the injury.He was however elated with the 2-0 victory by the Stars insisting victory was all that was needed.
