Robins said: "Nothing can change the result now and we have 12 more matches to go out and get points from. We have to regroup now and come back stronger next week."
He added: "I thought our support was great but it was just one of those days for us when you have to say you were beaten by the better side, albeit in circumstances we would rather not have happened.
"The sending off was the decisive moment. I have my goalkeeper saying he did not catch him and Peter (Lovenkrands) telling him the same afterwards.
"The referee has said he will take a look at it but he has told me that the law states 'trip or attempt to trip' although that is news to me. That was the decisive moment in the game."
