Alexander Isak walks back into St James’ Park on Sunday for the first time since leaving Newcastle, and Ladbrokes are marking the occasion with a boost for new customers.Sign up here before kick-off and you can back Isak to have a shot on target at 50/1, a market originally priced at 1/3. Land it and 10 x £5 free bets follow, on top of your returns at the original price.The Sweden striker joined Liverpool from Newcastle in a British-record £125m deal on deadline day last September, a year on from telling the club his relationship with them could not continue. He missed the corresponding fixture last season, so Sunday is the reunion Tyneside has been waiting for.If Isak hits the target, you winTo take advantage, head to Ladbrokes through our link and make a first deposit of at least £10 using a debit card. Then place a £1 single on Isak to have one or more shots on target at the boosted price of 50/1, before the 4.30pm kick-off.If he does, you’ll get 10 x £5 free bets within 24 hours of the market settling, along with your stake and winnings paid as cash at the original price. The free bets work on any sports market and expire after four days.Isak has a point to prove on his returnIsak’s first season at Anfield never got going. He arrived without a pre-season behind him after forcing his move through, then broke his leg in the act of scoring against Tottenham in December and lost almost four months. He finished with four goals from 22 appearances, only 13 of them starts.The version Newcastle remember is a different player. Isak scored 62 goals in 109 games for the Magpies, 54 of them in 86 Premier League appearances, and in his final season at St James’ Park he registered 46 shots on target across the league campaign alone.He is also the only senior striker Andoni Iraola has available, with Hugo Ekitike facing months out, and Iraola has spent pre-season demanding more pressing from the front line. Isak scored against Monaco and struck the base of the post against Como in Liverpool’s last two warm-up games. The reception on Tyneside will be hostile. He is unlikely to shrink from it.Understanding the offerTo qualify:Register as a new Ladbrokes customer before kick-off at Newcastle vs Liverpool (18+, UK and Republic of Ireland only)Make a first deposit of £10 or more (Neteller, PayPal, Paysafe, Skrill, pre-payment cards and certain debit cards are excluded)Place your first real money single bet of £1 on Alexander Isak to have one or more shots on target at 50/1, before the match startsThe stake is capped at £1Qualifying bets cannot be cashed outYou’ll receive:10 x £5 free bets if Isak has a shot on target, credited within 24 hours of the market settlingYour stake and winnings paid as cash at the original price of 1/3Nothing is returned if he fails to hit the targetKey terms and conditions of this Ladbrokes offer New customers only, 18+, UK and Republic of Ireland Offer runs until 4.30pm on Sunday 23 August Free bets expire four days after being credited Free bets can be used on any sports market, but not on eSoccer, Virtual Sports, Specials, Tote or Pools Free bets cannot be withdrawn as cash and the stake is not included in returns Free bets are not eligible for cashoutAbout the authorZack LaneZack Patrick Lane is an enthusiastic sports writer and lifelong Aston Villa supporter who passionately follows the beautiful game.
