International action once again dominates the Sunday schedule with eight Nations League matches taking place across the day.The Republic of Ireland and Wales are both in action, as they host Israel and Denmark respectively, while Norway face a tough trip to Portugal.talkSPORT BET – Bet £10 Get £40 In Free Bets + A Boost Token – CLAIM HERE*Bet of the dayRepublic of Ireland to beat Israel @ 19/20The Republic of Ireland will have been disappointed to draw 2-2 at home to Austria on Thursday after giving up a 2-0 lead, but they can make amends by beating Israel behind closed doors at the TSC Arena in Serbia.After a disappointing 1-0 loss to Kosovo in their Nations League Group B3 opener, Ireland defeated Israel 3-0 on matchday two before taking a point against Austria.Troy Parrott has been in excellent form, scoring three goals in his last two matches, while there has been able support from Adam Idah and Jack Moylan.Israel have collected just one point from their three matches and with just one goal scored, it is evident they are struggling in the attacking third.This looks like a prime opportunity for Ireland to pick up the win and potentially move to the top of the group, depending on the result between Kosovo and Austria.Bet builderPortugal vs Norway – Portugal to win, Joao Felix anytime goalscorer & Goncalo Ramos 1+ assists @ 17/2Portugal made it three wins from three in Nations League Group A4 with Thursday’s 4-2 victory over Denmark, a result which also extended head coach Jorge Jesus’s perfect start since taking charge in the summer.Visitors Norway let a 1-0 lead slip in Cardiff to lose 2-1 against Wales and that has left Stale Solbakken’s side third in the standings, having also lost to Portugal 2-1 in Oslo on matchday two.The Norwegians are too fragile at the back to keep a rampant Portugal at bay and it is hard to look past anything other than another win for the 2016 European champions.Key to this winning streak for Selecao das Quinas has been Joao Felix, who started and scored in the first two group matches before coming off the bench to net against Denmark.The 26-year-old looks capable of adding to his goals tally, with his teammate Goncalo Ramos potentially providing the assist.Ramos set up the opener in the win over the Danes and he can show his creative talents once again.AccaWales vs Denmark – both teams to score, Netherlands to beat Serbia & Greece to beat Germany @ 23/4Wales picked up their first points of Nations League Group A4 with Thursday’s 2-1 home win over Norway, a result which also means they have scored in six home matches in a row.The Dragons now host a Denmark side who beat them 2-0 on matchday two and have scored twice in each of their last four fixtures.Both teams to score looks like a solid bet for this clash in Cardiff.It has not been entirely plain sailing for the Netherlands in Group A2, but they have collected five points from three matches and their sole win came against Serbia.Oranje won 2-1 in Belgrade and they can once again account for the visitors, who have lost all three games to sit bottom of the pile.Round off this accumulator by backing Greece to defeat Germany for the second time in Group A2.Greece registered a 1-0 win in Augsburg on matchday two and they sit top of the pool after three matches, having also beaten Serbia and drawn against the Netherlands.Germany have made a slow start under Jurgen Klopp, having followed a draw against the Dutch with a loss to Greece and a win over Serbia.Klopp is still finding out what his best side is and they could be shocked again by a settled Greece outfit. 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+.
