World No 1 Novak Djokovic admitted on Sunday it will be bizarre to see his friend Ivan Ljubicic helping coach one of his greatest rivals, Roger Federer, this season.

"Yes, honestly, yes!" said Djokovic, when asked if he would find it strange to see the Croat as part of the Swiss legend's coaching staff. "But you know, again, we are professionals."
