Most of the footballing action on Sunday comes from the Nations League, while there are some international friendlies, too, so knowledge of the global game is important for the punting community.Here we pinpoint some betting options for Sunday, with focus on Jurgen Klopp’s first Nations League outing as Germany manager.talkSPORT BET – Bet £10 Get £40 In Free Bets + A Boost Token – CLAIM HERE*Bet of the dayDENMARK (-1) VS WALES ON HANDICAP – (8/5)Denmark players and fans were heartbroken that they failed to qualify for the last World Cup and there is a determination to puts things right in the squad of the former European champions.Expect a focused and ruthless Nations League performance at home to Wales. Denmark have scored nine goals in their last three home games and they beat Portugal in their last Nations League home gig.The last time Wales travelled to face decent opposition was to Belgium last year – and they conceded four goals.Backing Denmark minus a goal on the handicap for Sunday evening’s meeting at Parken Stadium, Copenhagen, is an attractive investment at 8/5.Bet builderGERMANY TO BEAT GREECE, OVER 3.5 GOALS, BOTH TEAMS TO SCORE NO – (29/4)Germany are starting a new era under the guidance of Jurgen Klopp and this could be a thrilling period for supporters of the four-time world champions.Klopp’s predecessor Julian Nagelsmann can consider himself unlucky – a VAR disallowed goal contributed to Germany’s World Cup exit – but Die Mannschaft should flourish with jaunty Jurgen in charge.Germany are already one of the best attacking teams on the international stage and Greece are probably going to have to draw upon all their trademark defensive discipline to keep the scoreline respectable at the WWK Arena on Sunday evening.Germany (and previously as West Germany) have won seven and drawn three of their ten meetings with Greece. The Germans have scored 12 goals in their last four matches against these opponents.A thumping home win can be expected, with the German fans demanding entertainment, so four or more total goals seems likely. The Greek’s lack of attacking intent – and dearth of forward quality – means they will probably fail to get on the scoresheet.AccaLITHUANIA TO BEAT AZERBAIJAN, AUSTRIA TO BEAT KOSOVO, DENMARK TO BEAT WALES, GERMANY TO BEAT GREECE – (6/1)A Nations League home-win accumulator on Lithuania, Austria, Denmark and Germany pays almost 6/1.Lithuania have been facing superior opposition to the teams which have been lining up against Azerbaijan. Punters should not be fooled into thinking Azerbaijan’s narrow recent victories over San Marino and Tajikistan count for much. Lithuania have more quality and look a big price for victory.Free-flowing Austria can be fancied to overwhelm a Kosovo squad which is woefully thin, while Denmark should have too much class for Wales. The last three meetings between these sides have resulted in a Danish win.Germany can be expected to thrash Greece, as the home players bid to impress new manager Jurgen Klopp.talkSPORT BET – Bet £10 Get £40 In Free Bets + A Boost Token – CLAIM HERE*Odds correct at time of publish and subject to change.Commercial content notice: Taking one of the bookmaker offers featured in this article may result in a payment to talkSPORT. 18+.
