Paes and Bopanna kept their off-court differences aside to outclass the Korean pair of Seong Chan Hong and Hong Chung in straight sets at the grass courts of Chandigarh Club last weekend.
"It came at the right time. Both Leander and Rohan played really well and it bodes well for them ahead of Olympics," Khanna said.
Asked about medal prospects, the veteran administrator said it should not be a surprise if India finish on the podium.
Last Saturday, the Indian pair of Paes and Bopanna dished out a dominating performance to trounce the visitors 6-3 6-4 6-4 in just one hour and 41 minutes to guide India into the World Group Play-offs.
The reluctant partners for the Rio Olympics did not face any competition from the Koreans in what was their only competitive match together before the Games.
