Barry Cowan says Milos Raonic was immaculate on serve during his victory over Gael Monfils at the ATP World Tour Finals, and this could be the time to finally beat Novak Djokovic on Tuesday.Raonic showed no sign of the leg injury that put his place in the ATP World Tour Finals at risk when he beat debutant Monfils handsomely at the O2 Arena on Sunday. Watch NOW TV Watch Sky Sports for just £6.99. No contract. Wimbledon runner-up Raonic made a flying start with a 6-3 6-4 Ivan Lendl Group victory over French showman Monfils. The world No 4, standing 1.96 metres tall and weighing in at nearly 100kg, moved surprisingly smoothly, and Cowan feels his performance put down a marker for Djokovic, who looked out of sorts during his three-set victory over Dominic Thiem. Highlights of Milos Raonic v Gael Monfils at the World Tour Finals Raonic has yet to record a victory in eight matches over former world No 1 Djokovic, including defeats at Indian Wells and Madrid earlier this year.Ive always thought if there was a player that would win a Grand Slam, and I think he is very, very dangerous. In the Djokovic group, he is the player that could potentially beat Djokovic, said the Sky Sports Tennis analyst.I think its really exciting about what could happen tomorrow. He has struggled against Djokovic in the past mentally, but you have to say that now is a good a time as any if he wants to beat him. Raonic was at the Sky Pad with Mark Petchey explaining his service action, how meditation helps his relax, and why he hates eating dates Cowan also feels the Canadian must play smart tennis in order to overcome his losing streak against the Serb.I think generally Djokovic likes playing big servers, so Raonic has got to be smart tactically, hes got to serve and volley, not the whole time, but he has to especially on the second serve, he said.In the final of Indian Wells he got stuck of being in a rut on his second serve and barely won a point. It will be a bit more competitive but the memory of that defeat will be there. Raonic was delighted after kicking off his Tour Finals with an impressive win over Monfils But Milos will be saying, Marin Cilic lost 14 times in a row against Djokovic and then beat him, so why cant I?. This is as good a chance as hes ever had. Hes got to be smart and the second serve will decide whether he can keep holding onto his serve.Check our game-by-game coverage from all group matches at the ATP World Tour Finals in London - including Milos Raonic against Novak Djokovic - on skysports.com/tennis, our app for mobile devices and iPad and our Twitter account @skysportstennis.Also See:Raonic sweeps aside MonfilsRaonic relieved about injuryDjokovic denies temper issueNow well see the real NovakAvery Bradley Clippers Jersey . -- Running backs Darren McFadden and Rashad Jennings were back at practice for the Oakland Raiders on Wednesday despite being hampered by hamstring injuries.
