Two-time French Open winner Nadal extended his clay court winning streak to 63 matches with the win over Argentinean Chela.
"It was very nice to come back here and play the first match like this. I felt very comfortable on court. I could have served a little bit better but for the rest I'm very happy," Nadal said.
The Spaniard added he would not take anything for granted when he takes on Belgian Kristof Vliegen for a quarter-final spot.

"It is going to be a tough match. He is a very talented player. He beat [Paul-Henri] Mathieu and [Marat] Safin," he added.
Nadal, who has also won the Monte Carlo Masters for the past two years, got off to a racing start breaking in the very first game before comfortably holding serve to take an early 2-0 lead.
The first set was all about the Spaniard and he never hit top form with Chela's inconsistency costing him. Even when Nadal dropped his serve with an uncharacteristic double fault Chela hit top double faults in the very next game to throw the first set away.
Nadal again broke in the opening game of the second set before running away with it securing his place in the third round on his third match point.
