The Racing Metro No.9 has had to play second fiddle to Jean-Marc Doussain in Les Bleus' first three games of the Championship.
But after returning to his club last weekend and guiding them to a 25-15 win over defending top 14 champions Castres, Machenaud could be in line for his first start of the Championship against Scotland this weekend.
And the 25-year-old admits his return to club duty last weekend brought the best out of him.
"It did me some good. You have to play full matches in order to gain some rhythm," he said.
"I only played 40 minutes against Wales, and 20 minutes in the first two matches of the tournament.
"I really wanted to play a whole match, for my confidence, for my rhythm, to have that intensity.
"This week will be a bit complicated but we will all recover well and be ready in time to take on Scotland."
