Rangers will meet Old Firm rivals Celtic at Ibrox in a Scottish Cup quarter-final on Sunday.The Gers booked their place in the last eight with a 5-1 win over St Mirren in the previous round, while Celtic beat Dundee United 4-0 to progress to this stage.After a troubled start to his time in charge of Rangers, head coach Derek McInnes will be hoping a win over their Old Firm rivals Celtic can act as a catalyst for better things to come.Rangers vs Celtic quick tipsCeltic to win the tie – 5/6 with SBKOver 2.5 goals and both teams to score – 5/6 with MidniteBenjamin Nygren to score anytime – 7/4 with BetfredRangers vs Celtic predictionsWith no wins in his first four games at Ibrox, things couldn’t have got off to a much worse start for new Rangers head coach Derek McInnes. Then just as things looked like picking up, along came the Jablonec debacle that saw the Gers dumped out of the Conference League in the third round of qualifying. That defeat felt like rock bottom. It was a humiliating new low, and since then Rangers have won four matches in a row in the Scottish Premiership.But before fans from the blue side of Glasgow can get too carried away, the manner of those wins has to be taken into consideration, with all four coming by just a one-goal margin.The Gers are already five points behind Celtic in the Scottish Premiership after just six matches, and another defeat to their bitter rivals will immediately put McInnes back under the pump again.Celtic’s start to the season has been solid. But like Rangers, they also suffered a humiliating European exit. The Bhoys have won eight from nine in all competitions this season. This includes six from six in the Scottish Premiership, where they sit top of the table on maximum points. They also beat Dundee United in the second round of the Scottish Cup and they beat LASK Linz 3-0 in the first leg of their Champions League playoff qualifier.However, things went horribly wrong in the second leg. Celtic took an early lead in the match to lead the tie 4-0 on aggregate, but then the wheels fell off and the Bhoys conceded five unanswered goals to lose the tie 5-4. The response from Martin O’Neill’s team was instant. They won four successive Premiership matches against Falkirk (2-1), Aberdeen (3-0), St Mirren (2-1) and St Johnstone (1-0).Similar to Rangers, after such a humbling defeat in Europe, Celtic are also only one bad result away from their next crisis.Rangers vs Celtic tipsBoth teams will be looking to win the first Old Firm clash of the season and lay down a marker for the rest of the campaign. Our Rangers vs Celtic betting tips follow:Celtic worth backing to progressRangers need the win badly. They’ve had an awful start to the season and a win over their main rivals will go a long way to repairing some of the damage.However, Celtic look to be miles ahead of their Glasgow rivals. One result aside, they’ve had a good start to the season, while Rangers look all over the place.Furthermore, Rangers are without Tuur Rommens, Youssef Chermiti, Jose Cifuentes and Lawrence Shankland through injury.The Bhoys are good value at 7/5 to win in 90 minutes. But given this is a cup match and it’s at Ibrox, we are backing them to win the tie by any method. Celtic to win the tie at 5/6 with SBK One goal to break match wide openGiven the situations at both clubs, there is a slight possibility that this becomes one of those matches neither team wants to lose.However, Derek McInnes needs a big win to try and bring some harmony back between the club and the supporters. He could also do with a statement victory to consolidate his own position. This is his perfect opportunity. At home to Celtic, on a four match winning streak, and with no away fans present at this match.Rangers will have to go for the win, and one goal should blow the match wide open and see both teams go flat out. Go for over 2.5 goals and both teams to score at 5/6 with Midnite Back Nygren to continue scoring formBenjamin Nygren has started the season in sensational form for Celtic. He has scored five goals and provided six assists in his nine appearances in all competitions. The Swede was left on the bench against St Johnstone on Wednesday and only played the final 23 minutes, so he should be fresh for Rangers.Even in his brief midweek appearance, the Bhoys looked far more dangerous in attack and if Nygren can replicate that against the Gers, he is worth backing to score. Back Benjamin Nygren to score anytime at 7/4 with Betfred Rangers vs Celtic predicted lineupsRangers expected lineup: Pandur; Sterling, Fernandez, Makhanya, Penrice; Raskin, Neil; Bouanani, Naderi, Gassama; Miovski.Celtic expected lineup: Johnstone; Donovan, Murray, Trusty, Scales; McGregor, Baur; Hassan, Nygren, Duran; Hogh.Rangers vs Celtic latest oddsFind the latest Rangers vs Celtic betting odds here.
