The Robins earned a vital midweek victory at Yeovil with Thompson picking up the man-of-the-match award for his all-action display.
And that triumph, secured thanks to two late goals, moved them to within a point of the automatic promotion places and continued their impressive form against the league's best sides.
"We have been fantastic against the top teams and now the last eight games are huge for us," the 22-year-old told Press Association Sport.
"Every game we will approach like a cup final and after eight games we'll see where we are.
"It was an important win for us. They were three massive points and a great performance. The last few games had been a bit disappointing for us, we had been a bit brittle. Conceding the goals like we did was very unlike us but to get the clean sheet at Yeovil was important.
"We worked hard all season and you can see late in games we really become a lot more dominant."
