United drew 0-0 in San Sebastian.
"I thought it was a typical away performance in Europe," Crerand told manutd.com. "We went there with experience of setting out our stall and not losing a goal. I thought the back four were tremendous. I thought Fellaini was terrific as well, which is a big lift for his confidence - despite the red card, which I thought was harsh.
"We are going home disappointed but when you go away in Europe, particularly to Spain where our record is awful, it's not a bad thing to be disappointed with a draw."
