The new football season is underway in both England and Scotland and there is plenty of action taking place throughout Sunday.Sheffield United head to Mansfield Town in the EFL Cup while both Celtic and Rangers take to the field in the Scottish Premiership. On the continent, there are also league games kicking off in Portugal, Germany and the Netherlands.Here’s our best bet of the day, best value bet builder and a longshot 9/1 acca.talkSPORT BET – Score up to £30 in free bets – CLAIM HERE*Sunday football tipsBet of the DayRangers to beat Hibernian @ 1/2Rangers endured a difficult evening in Poland on Thursday, losing 2-1 to Jagiellonia Bialystok in the third qualifying round of the Europa League and will be eager to bounce back on Sunday.The Gers host Hibernian at Ibrox in the Scottish Premiership and new boss Derek McInnes will know a home victory is a must to get momentum going after an opening day draw with Dundee United.Hibs lost their first game of the campaign 2-1 at home to Motherwell and, though they recovered to defeat Shkendija in the Conference League in midweek, Gers should have enough quality to record an important three points and kickstart their title push.Bet BuilderCeltic to beat Kilmarnock, Kasper Hogh anytime goalscorer & over 8.5 corners @ 13/5Celtic started the season with a 1-0 home victory over Dundee and now head to Kilmarnock looking to make it two wins from two.Killie scored three goals in their Scottish Premiership opener against St Johnstone but lost 4-3 and, despite having home advantage against the Bhoys, will likely have to wait for their first points of the season.Celtic are favourites and can win thanks to new striker Kasper Hogh. The summer signing from Bodo/Glimt missed some gilt-edged chances last week at Celtic Park, but was constantly in the right place at the right time and should be confident of opening his account at Rugby Park.Looking at set-pieces, Celtic’s win featured 13 corners and Killie’s match saw nine. While Martin O’Neill’s side are expected to dominate on Sunday, there should be chances at both ends, so backing over 8.5 corners when the two teams meet at Rugby Park could prove a smart bet.AccaSheffield United to beat Mansfield Town, Feyenoord to beat Sparta Rotterdam, Porto to beat Alverca & Dynamo Dresden to beat Nurnberg @ 9/1Sheffield United’s focus this season will be on mounting a promotion push, but a win against Mansfield Town in the first round of the EFL Cup can set Chris Wilder’s men up for a strong start to the campaign.The Blades have enjoyed an unbeaten pre-season, winning four in six, and can take this strong form into the clash at the One Call Stadium.Feyenoord finished 19 points behind champions PSV in the Eredivisie last season, so will be aiming for a winning start when they head to Sparta for the Rotterdam derby on Sunday.In Portugal, Porto began the defence of their title with a home match against Alverca and they are big favourites to record a victory.The Bundesliga 2 campaign will be well underway come Sunday when Dynamo Dresden travel to Nurnberg.Dynamo claimed a 2-0 win at the Max-Morlock-Stadion last April and can repeat the feat again in their season opener on the road.talkSPORT BET – Score up to £30 in free bets – CLAIM HERE*Odds correct at time of publish and subject to change.Remember to gamble responsiblyA responsible gambler is someone who:Establishes time and monetary limits before playingOnly gambles with money they can afford to loseNever chase their lossesDoesn’t gamble if they’re upset, angry or depressedGamCare – www.gamcare.org.ukGamble Aware – www.gambleaware.orgFor help with a gambling problem, call the National Gambling Helpline on 0808 8020 133 or go to www.gamstop.co.uk to be excluded from all UK-regulated gambling websites.Commercial content notice: Taking one of the bookmaker offers featured in this article may result in a payment to talkSPORT. 18+.
