Gillingham boss Martin Allen insists there will be no let up from the Gills despite them all-but sealing automatic promotion to npower League One with victory over Rotherham.

Former Millers striker Deon Burton netted the only goal of the game in the 22nd minute as the Gills extended their lead over fourth place from 10 points to 11. The 36-year-old striker, who played for Rotherham seven seasons ago, buried Danny Kedwell's flick on from a long Chris Whelpdale throw for the winner in the first half.

Gillingham are also eight points clear of Port Vale in second with four games remaining to their five, however boss Allen will not be celebrating anything just yet. He said: "We need to keep doing it right and keep going. We cannot let our standards drop. Rotherham are good, they have invested a lot, but they weren't that good."

Allen continued: "They gambled as you do at the end so it was tricky and testing. Apart from one long-range effort though, they never got near our goal. It was a top, top performance. We made the decision at Fleetwood (last time out) that there is no room for excuses, let up or sleep because Rotherham had a day extra to recover.

"We dominated from start to finish and we should have had loads of goals. Deon will get the headlines but this is a squad, on and off the field we were very, very strong. Other results have gone our way. Everybody knew it was April Fools' Day and there was no way we were going to be the fools."

Despite the defeat Rotherham are still firmly in the play-offs in sixth and, with games in hand on those around them, Millers boss Steve Evans is remaining cool, calm and collected.

"I am not worried about seventh place," he said. "We just have to grind out and play our game. We don't appear to get decisions and sometimes that can be why you get promoted.

"I think that we have had a raw day from the official and when he looks back I'm sure he will be disappointed with his performance. I am not questioning his integrity, he's a very honest guy. We had a stonewall penalty ten minutes from time and any other week it's a penalty.

"Gillingham dominated us in the first half. They missed a couple of chances which could've sealed it and, after half-time, obviously they had a few more. But that was because we were pressing forward and having a little gamble so we've got to be disappointed that we pushed forward a lot and left with nothing.

"I don't know what the statistics will show in the second-half, but it will show a very, very high percentage of possession and chances."
