Men's top seed Novak Djokovic talks after his first round win over Jerzy Janowicz at the US Open Monday (29 August).

SOUNDBITE (English) Novak Djokovic:

"Look, each day presents us some kind of challenges that we need to overcome, accept and overcome. It wasn't easy today playing against Jerzy for the first time. He's a very, you know, potent player, powerful serve, big forehands. Unpredictable really. Play well as he did in the second set and he can make a couple double-faults in a row in the important moments. It's really up and down. That's why it wasn't easy to keep the concentration. But I thought I've done well in the third and fourth to bounce back from the dropped second set. It's an opening match, night session. After all I've been through in last couple of weeks, it's pleasing, of course, to finish the match and win it. I'll try to look positive and just think about the next day."
