BERLIN -- Thomas Mueller scored a hat trick as Bayern Munich opened its German Cup defence with a 5-0 win over fourth-tier side BSV Rehden on Monday. "Such a game is always dangerous," Bayern coach Pep Guardiola said. "So were happy." Xherdan Shaqiri opened the scoring in the 18th, deflecting in Arjen Robbens shot from close range after the Rehden defence failed to clear the ball. Mueller was unmarked when he scored just before halftime with a header from Rafinhas cross. Rehden goalkeeper Milos Mandic denied Mario Mandzukic with an acrobatic save early in the second half, and Mueller hit the crossbar from the resultant corner. However, the Bayern attacker dusted himself off to make it 3-0 from the penalty spot after he was brought down in the area in the 58th, and he completed his hat trick in with a header in the 64th. Mueller was still furious with himself for missing another chance late on, before Robben wrapped up the scoring two minutes from time. "Were not perfect yet," Robben said. "Were not at 100 per cent but thats normal. Were ready for the Bundesliga regardless. Well be there on Friday." Earlier Monday, Klaas Jan Huntelaar scored one goal and set up another for Schalke to defeat fifth-tier FC Noettingen 2-0 to advance to the second round. Huntelaar struck in the 30th minute but the visitors were made to wait until the fourth minute of injury time before the Dutchman could set up off-season signing Leon Goretzka to secure the result. "They played well in the first half, hit the crossbar twice," Huntelaar said. "We were bad, you have to be honest." Second-division side Paderborn defeated third-tier MSV Duisburg 3-2, and another second-division side, Union Berlin, won 2-1 at third-division Jahn Regensburg. Nike Shoes Cheap Wholesale .

"I just love the fact I am in contention and have an opportunity in my first tournament of the year here in Abu Dhabi," Mickelson said.Niall Quinn says the Republic of Ireland are starting to believe World Cup qualification is possible after their victory over Austria helped them maintain their unbeaten start. The odds of reaching the 2018 tournament in Russia were stacked against Ireland when they were drawn in a group alongside Wales, Serbia and Austria.However, Irelands 1-0 victory in Vienna on Saturday sent them top of Group D, having secured 10 points from their opening four games. And while Quinn admits that Irelands start has come as a shock, he said Martin ONeills ability to get the best out of his players is the reason why they are in such a strong position.It has taken me by surprise because its a really tough group, Quinn said. Even Serbia look good and suddenly theres four teams in it so its going to be difficult. Republic of Ireland manager Martin ONeill was proud of his players as they became the first away team to beat Austria in a competitive match in Vienna in But ONeill has got a clique going on now. They all believe and the motivation he has brought into that side, and the way that theyre bringing it out in performances, means were starting to believe ourselves.I honestly think fans are of the opinion that the perfect man is managing this team, and that theres another trip on its way in two summers time.Irelands victory over Austria was their first since 1963, and they had James McClean to thank after the West Brom winger netted in the second half. Highlights of the Republic of Irelands World Cup qualifier against Austria.dddddddddddd McClean is viewed as a divisive figure - predominantly down to his decision not wear a poppy around Remembrance Day - but Quinn believes the 27-year-old has matured as both a man and a player.James wasnt afraid to come out and say we have to kick on and win the group now, others would just be cautious, said Quinn.Hes as honest as you like, people might disagree with his political principles, but the lad gives absolutely everything hes got.Hes starting to get clever with it and understand the game more. His work-rate is always superb, he works so hard up and down that left side in every game he plays. Harry Arter was pleased to make his competitive debut for the Republic of Ireland and hopes for more wins following victory over Austria. Hes now reading things better, and he saw that opportunity open up as soon as [David] Meyler took the ball. What a ball from Wes [Hoolahan], but still a lot of work to do, and James is playing like a player who just wants more of that now.Quinns praise led fellow Sky Sports pundit Dean Saunders to remind the ex-Sunderland chairman of how he first brought McClean to England in 2011.I signed him in a pub, thats not to say hes a pub player - but his agent met me in a pub, Quinn added.Its one of those things, its great. To see his career develop and blossom, hes had a few bumps to try and get over - but its going well for him.Theres no better feeling. To think that hes gone away to Austria tonight and has scored the winner for his country in such a big game, thats fantastic for him.
