Novak Djokovic is learning to expect the unexpected at Wimbledon but is making sure he keeps his own game under control.
The world number one started his tournament today with a 6-3 7-5 6-4 win over Florian Meyer to move into the second round.
He will not be joined by fellow big name Rafael Nadal, with the 12-time grand slam winner having been knocked out yesterday.
The Spaniard's loss to Steve Darcis merely served to remind Djokovic of the dangers that are out there and he is doing his best to avoid them.
"It's a grand slam and I am focusing on my matches," he said.
"In the opening rounds it's obviously very dangerous for the top players because on the other side is someone with nothing to lose.
"You cannot take anything for granted. You have to be grateful for being in this position, work even harder and stay there."
Djokovic is the top seed in London and the highest player he could possibly meet before the final is David Ferrer.
The fourth-seeded Spaniard was crushed by Nadal in the French Open final but is becoming a real presence at the business end of tournaments and launched what he hopes will be a long run today with a four-set win over Martin Alund.
The dark horse of the draw could be the 2009 US Open winner Juan Martin del Potro.
The Argentinian has suffered terribly with injuries and form since that Flushing Meadows success, but looked arguably as good as he has done in four years as he brushed past Albert Ramos 6-2 7-5 6-1.
"The level is high and all the top four or five can be beaten, they can lose to everybody. I have to do my own draw and go match by match and see if I can go far," Del Potro said.
