LONDON -- Novak Djokovic was embroiled in a tetchy exchange with reporters after defeating Dominic Thiem in his Tour Finals opener.The Serb -- who was overtaken as world No. 1 by Andy Murray this week -- had earlier appeared to vent his frustrations after losing a first-set tiebreaker in his 6-7 (10), 6-0, 6-2 victory.He nearly tagged his coach Boris Becker with a ball seemingly struck in the direction of his players box, and was given a code violation by chair umpire Carlos Bernardes.It was suggested to Djokovic in his postmatch news conference that he had been close to potentially hitting a spectator in the crowd, which could have resulted in him automatically defaulting the match.It didnt go down well with him. You guys are unbelievable, he said. Youre always picking these kind of things.Im close? Im still not suspended, so if Im not close, Im not close. It could have been [serious], yes. It could have snowed in the O2 arena, as well, but it didnt.Im the only player that shows his frustration on the court? Thats what you are saying?It is not an issue for me. Its not the first time I did it.Indeed, Djokovic also flirted with more serious punishment when he vented his frustrations in the Roland Garros quarterfinals earlier this year.After missing a break point in the second game of the third set of that 6-3, 7-5, 6-3 win against Tomas Berdych, Djokovic went to smash his racket into the dirt, only to see it slip out of his hand and fly into the back wall on Philippe Chatrier Court.Djokovic admitted at the time he was lucky -- had he hit the nearby line judge, who was forced to take evasive action, he could possibly have been disqualified.Instead, he escaped with a warning for racket abuse after quickly apologizing to chair umpire Eva Asderaki Moore in Paris.[It was a] high intensity, high level of tennis in the first set, Djokovic continued in his news conference. We didnt really give each other too many chances. I think we each only had one break point. We both went for shots. A lot of long rallies. It was over an hour, the first set.When I had the great comeback of saving six set points, then I didnt manage to win that first set, of course youre frustrated. On the other hand, you know, I think I managed to kind of compose myself and really gather all my attention and concentration to what was coming up after that.The great start of the second set helped me to regroup.Djokovic is chasing a record-equaling sixth Tour Finals title in London, which would see him immediately regain the No. 1 ranking form Murray.

The 15th-ranked Canadian men lost the opening two games of their European tour: 19-15 to No. 17 Georgia and 21-20 to No.Defence coach Paul Gustard admits England still have plenty to work on despite the promising start under coach Eddie Jones. England began their Six Nations campaign with a hard-fought 15-9 win over Scotland at Murrayfield on Saturday, although there was little sign of the high-tempo rugby that Jones is keen to implement in his new side.Jones has said England will get fitter under his tutelage and Gustard, brought in by Jones as part of an overhaul of the entire coaching staff, said circumstances dictated much of Englands approach to the game. Gustard says Italy have progressed hugely since joining the Six Nations We want to increase the tempo, but unfortunately due to the weather conditions, due to perhaps the time we spent together, due to how good Scotland were defensively in the first half, we werent able to get that stranglehold on the game in terms of our tempo, Gustard told Sky Sports News HQ. Its again something we will try to earmark this weekend and in the games after that.The first-half wasnt perfect from a defence coach point of view. We got cut three times, two in and around the line-out at the back of the maul, so its something weve been trying to work on this week. England head coach Eddie Jones says hes likely to make changes to the team that beat Scotland which included James Haskell The second-half improved significantly and I think we looked quite comfortable in terms of containing Scotland, who have a very good attack and they are a well-coached team.ddddddddddddNext up for England is a trip to Rome to face Italy in their second straight away game and Gustard says he is focusing his efforts on containing No 8 Sergio Parisse, who remains the heartbeat of the Italian team.Italy have progressed a lot. Theyve beaten everyone else but England in the Six Nations, he added. Italys Sergio Parisse (right) is dejected after missing a last-gasp drop goal attempt against France Parisse has been their talisman - he can do the unexpected, hes not a traditional forward, he wants to step up as a first receiver, he wants to try a drop goal, he wants to put a chip in, so hes a target for us to try and neutralise. There are a lot of other good players around him. His legs arent quite what they used to be in terms of the amount of involvement he has, but theyve got two wings that have got a lot pace and the 10 looked a tidy player at the weekend as well.Theyre going to be a good team, theyre certainly well coached and will be diligent in defence.
