The pair played together for victory over Rayo Vallecano.
"This issue of a conflict I have heard many times - it is absurd," said Roura.
"Currently the relationship between the two is just like it was a few months ago. I mean, very good."
Villa has enjoyed a fruitful week, his goal last night coming days after he scored against AC Milan as Barcelona made an astonishing comeback to qualify for the quarter-finals of the Champions League.
Roura continued: "I've always said that David is a very important man for us. It's a great joy for us to see him score because he brings a lot to the team."
