Robinson replaced Nathan Tyson in the final 15 minute of the game, and the former Milwall man kept his cool to slot past onrushing goalkeeper Mark Cousins and net a dramatic 90th minute equaliser at the West Homes Community Stadium.
Robinson, who finished last season as the side’s joint-top goal-scorer with 12 goals, netted twice in the team’s 4-3 victory over Northampton Town as well as the opener in the narrow 2-1 defeat to Mansfield Town, and Fielding believes the forward is in top form, ahead of the 2012-13 campaign.
He told Rams Player: “It was nice for Theo to score right at the end; it keeps our mini unbeaten run going.
“Theo cannot stop scoring, and that is what he is paid for.
“I’m paid to stop goals going in, whereas he’s paid to score them. Unfortunately tonight we have conceded two goals, as primarily we want to keep clean-sheets, but life is not perfect and we’ll move on and learn from tonight.
“There are still two week until the season starts, so there is still time for us to work on a few things.”
Meanwhile, Fielding believes the Rams’ trip to East Anglia was the perfect opportunity for the team to get to know and welcome summer recruits Paul Coutts, Michael Jacobs, Richard Keogh and James O’Connor, as well as build on the side’s team spirit.
He added: “It has been really good to get away; we have all been hanging out together playing golf and snooker.
“I think the Gaffer has got it spot-on, three days away as been fantastic.
“We don’t particularly want to be travelling across Europe this time of year; we do enough travelling during the season.”
