The League One club were beaten 2-0 by the Blues in the third round of the FA Cup at Stamford Bridge in a match where the visitors may have been unlucky not to receive a penalty when Ramires tangled with Kevin van Veen in the box.
The spot kick did not come the way of the Iron, disappointing Robins, but he was all-in-all happy with the performance against a mare than capable Chelsea lineup.
"I think we gave a really good account of ourselves and tried," he said.
"I am proud (of them). I think they were good. They're a good set of lads and I was just hoping we'd get a goal. We've given everything we could.
"(We) Had one or two opportunities and the goalkeeper's made some good saves, a penalty shout.
"It's very difficult as they filmed it (the penalty shout) from the top of the stand.
"The analyst thought it was a penalty. It was just one of those things I think. Sometimes when you come to places like this you get the decision from the referee and we just didn't get it today.
"There's some really good players there. We've had injuries to key players and we're hoping for a decent second half to the season to get some continuity going."
