This has been a turbulent season for Celtic, but it could still end with two trophies in the Parkhead cabinet. A place in the Scottish Cup final is up for grabs when they face St Mirren on Sunday.Will Martin O’Neill’s men progress to the tournament showpiece as expected, or can St Mirren spring a surprise in this semi-final?Celtic to win by one goal – 11/4 with 247BetUnder 2.5 goals – 6/4 with MidniteBenjamin Nygren to score any time – 10/11 with CasimbaCeltic vs St Mirren oddsFind the latest Celtic vs St Mirren betting odds here. All odds are provided by our recommended football bookmakers and are subject to change.Celtic vs St Mirren predictionsA league and cup double can never be sniffed at, not even for a club as accustomed to domestic glory as Celtic. With just a few weeks of the season remaining, the Hoops are in the mix for success in both competitions. That does not even go halfway to explaining the campaign they have had, however. Whatever happens from here, this is the sort of season that Celtic will not want to repeat in a hurry.They started 2025/26 with Brendan Rodgers in the dugout, since when Celtic have made three managerial appointments.One of those was the ill-fated decision to hire Wilfried Nancy, who lasted in the job for just 33 days. On either side of Nancy’s tenure sit two unlikely spells at the helm for Martin O’Neill, a 74-year-old veteran whose prior experience of club management since 2013 amounted to five months at Nottingham Forest.And while it is true Celtic can still end the season with two trophies, that is very much the outlook of those whose glasses are half full.Another way of looking at it is that Celtic are in danger of winning nothing for only the second time since 2009/10. Worse still, they are currently third in the Premiership table, meaning 2025/26 could bring their lowest finish in more than 30 years.As if that was not enough, Celtic were eliminated from the Europa League in the knockout phase play-offs and lost the Scottish League Cup final to St Mirren, with whom they will do battle in the Scottish Cup semis this weekend. With Dunfermline Athletic and Falkirk the other two teams in the last four, Celtic are odds-on favourites to win the tournament. But that League Cup final defeat by St Mirren is proof that the Bhoys should take nothing for granted.True, that loss came during Nancy’s short-lived stint in the hot seat. Celtic have improved since O’Neill’s return for a second time, and they beat St Mirren in the Premiership last weekend to keep the heat on Heart of Midlothian and Rangers above them.It was only a 1-0 victory for Celtic last time out, though, and that was when they had home advantage at Parkhead. In fact, all three league games between the pair have finished 1-0 to Celtic, which suggests another tight game at Hampden Park on Sunday afternoon.Celtic vs St Mirren betting tipsWill Celtic or St Mirren reach the Scottish Cup final at Hampden Park on Sunday?Another narrow Celtic winMight we see Celtic defeat St Mirren 1-0 for the fourth time this season? It is definitely a possibility.The Saints are in danger of going down to the Championship, but they have held their own in each of their four meetings with the Hoops, none more so in that 3-1 triumph in the Scottish League Cup final.Interestingly, they have not lost to Rangers by more than a single goal either, while their four games against Hearts have yielded two draws and a win.St Mirren seem to raise their game against the bigger teams, so Celtic will not have everything their own way on Sunday. However, they should ultimately have too much for Craig McLeash’s men. Choose Celtic to win by one goal at 11/4 with 247Bet Low goal count?St Mirren will look to make life difficult for Celtic on Sunday, as they have done in their league matches against them.O’Neill’s side will have to be patient as they attempt to break down what can be a stubborn St Mirren rearguard.Celtic have not really been blowing teams away of late. In six of their last seven league games, they have scored two goals at most.We anticipate a relatively tight and low-scoring affair at Hampden. Celtic should get over the line, but they are unlikely to do so in a one-sided, goal-laden encounter. Go for under 2.5 goals at 6/4 with Midnite Nygren on target?Benjamin Nygren is not a striker, yet he is Celtic’s top scorer by some distance this term.The Sweden international needs one more goal to reach 20 for the campaign in all competitions, and we reckon he will hit that milestone this weekend.Nygren has not scored in any of his last five outings, but while form is temporary, class is permanent. Nygren did not play in the League Cup final, so he will be doubly determined to make his mark on this match at Hampden. Select Benjamin Nygren to score any time at 10/11 with Casimba Celtic vs St Mirren predicted lineupsCeltic expected lineup: Sinisalo; Ralston, Trusty, Scales, Tierney; McGregor, Oxlade-Chamberlain; Yang, Nygren, Forrest; Iheanacho.St Mirren expected lineup: George; Donnelly, Gogic, Freckleton; O’Hara, Devaney, Campbell, John; Phillips; Ayunga, Mandron.
