Arsenal scored three goals in seven minutes to seal an emphatic 4-1 victory over struggling Sunderland at the Stadium of Light.Alexis Sanchezs opening goal was cancelled out by Jermain Defoes second-half penalty, but substitute Olivier Giroud struck twice before Sanchez wrapped up the win with his second goal.The defeat means Sunderland have made the worst-ever start to a Premier League season, and piles more pressure on manager David Moyes. Here, we look at five talking points from the game. Arsenal hit four to go top Match report from Arsenals 4-1 win over Sunderland. Return of GiroudWhat must Giroud have been thinking when Sanchez leapt above Lamine Kone to head home Arsenals opener? The Frenchmans aerial prowess has always felt like a unique strength among Wengers forwards, but here was their makeshift frontman rising above Sunderlands 6ft 1in centre-back to power the ball past Jordan Pickford.But while Girouds status has taken a hit during his time on the sidelines, his second-half appearance was a timely reminder of his qualities. After instinctively hooking Kieran Gibbs cross into the net with his first touch, he sent a glancing header past Pickford with his second.Thierry Henry described them as two great finishes in the Sky Sports studio, adding: He has been injured and people doubt him but you have to give him his credit. At the beginning of the season I said that I would have both him and Sanchez up front. You can play the Arsenal way, but you can also play long. Sanchez may be the new first-choice, but Giroud gives Arsenal options. Watch highlights as Arsenal beat Sunderland 4-1 at the Stadium of Light Sunderland on the slide?The Stadium of Light was bouncing after Defoes spot kick pulled them level, but the jubilation was short-lived. Moyes men have now taken just two points from their first 10 games of the campaign. It is the worst-ever start to a Premier League season, and angry fans were heading towards the exits long before the final whistle. Worst-ever PL start Sunderland have made the worst start to a season in Premier League history. Moyes insists they are doing everything they can to turn things around, but there was little cause for optimism in this performance. The Black Cats only mustered three shots on goal across the 90 minutes - their worst return of the season so far - and Sky Sports pundit Niall Quinn fears his former club are already doomed.They looked lost at times trying to do the pass and movement, he said. They had a brief flurry in the second half but quite frankly the way this team is going now it feels like death by a thousand cuts the way theyre playing. Theyve got to something radical and different now. The fans would react better to a more direct approach. David Moyes said his side are doing everything they can to turn their poor form around Does Ox deserve a starting spot?Alex Oxlade-Chamberlain scored twice in Arsenals EFL Cup win over Reading in midweek and Theo Walcotts injury gave him another chance to impress against Sunderland. The 23-year-old is desperate to nail down a starting spot in Wengers team, and there were certainly positives to take from his performance.He produced the assist for Sanchezs opener by bursting past Duncan Watmore and delivering a pinpoint cross from the right, and there was also plenty of hard work off the ball. At one point he raced back into his own half to steal possession from Wahbi Khazri and halt a Sunderland counter-attack, and in total he made twice as many tackles (four) as any of his team-mates.There were, however, moments when he should have done better in front of goal. He dragged one effort horribly wide after being released by Ozil in the second half, and he seemed caught between crossing and shooting when he broke free again a few minutes later. He might need to show greater conviction to make the place his own. Alex Oxlade-Chamberlain provided the assist for Arsenals first goal Elneny impressesArsenal have fierce competition for places in central midfield, and with Santi Cazorla injured and Granit Xhaka suspended, Mohamed Elneny certainly took his opportunity to impress alongside Francis Coquelin. The Egyptian dictated the play from start to finish.He completed 91 of his 97 passes, nearly twice as many as any other player, and he was involved in the build-up to Arsenals first and fourth goals. Elneny constantly made himself available to team-mates, and Premier League tracking data showed he covered more ground (11.15km) than any other player. Even with a fully-stocked midfield, Wenger might find it hard to leave him out. Arsene Wenger praised the quality of Arsenals goals against Sunderland Is Gibbs first-choice?Walcott and Cazorla were joined in Arsenals treatment room by Nacho Monreal, giving Kieran Gibbs his first Premier League start since March at left-back. The 27-year-old was assured defensively and played an important role in Arsenals late rally.He provided the cross for Girouds first goal, laid on another scoring chance from which Ozil should have netted, and struck the post with a powerful shot in the build-up to Sanchezs second. Gibbs has had to be patient, but on this evidence he could be set for the run in the team he has been waiting for. Watch NOW TV Watch Sky Sports for just £6.99.

It was followed by a line advising players to leave all expensive jewelry at home, not to bring large sums of money and not to use ATMs.A second section titled health and performance has basic tips like drinking only bottled water and avoiding the consumption of ice. It also warned: Eat all meals in the meal room. DO NOT order room service and DO NOT eat outside of the team meal room.The precautions the Texans have provided players are not uncommon for any foreigners traveling to Mexico. Executives visiting the city for business are often given the same warnings from their companies to avoid leaving their hotels without ssecurity.dddddddddddd.The rule about room service could be related to a memo the NFL sent to its players earlier this year warning that some meat produced in China and Mexico may be contaminated with clenbuterol, a banned steroid. That memo, sent by the league office, said that consuming large quantities of meat while visiting those countries may result in a positive test for clenbuterol. The memo told the players to please take caution if you decide to consume meat, and understand that you do so at your own risk.Clenbuterol has been banned in Mexico as a growth enhancer for cattle but is suspected to still be in use there.The Raiders did not receive such a memo, but several players said they would not eat room service while in Mexico.I always bring my own food anyway, Oakland defensive tackle Dan Williams said. Im on a strict diet so I have to watch what I eat. No room service for me. I cant afford to sneak and cheat.---AP Sports Writer Josh Dubow contributed to this report.---For more NFL coverage: http://www.pro32.ap.org and http://www.twitter.com/AP-NFL ' ' '
