Tuesday night football brings the second leg of the Championship play off semi final as Southampton host Middlesbrough at St Mary's Stadium, with an 8pm kick off and a place at Wembley on the line.
The tie remains level at 0-0 after a first leg at the Riverside where Middlesbrough controlled large periods but failed to take advantage. Daniel Peretz produced four saves for Southampton while Taylor Harwood Bellis also struck the crossbar late on as the Saints escaped Teesside still level in the tie.
The added backdrop of Spygate, following Southampton's EFL charge for allegedly spying on a Middlesbrough training session, has only increased attention around one of the Championship's biggest matches of the season.
Southampton arrive unbeaten across their last 20 matches in the Championship and remain strong at St Mary's. Across the last eight games they rank ninth in the Championship for xPTS with 12.23 while averaging 2.00 xG per game.
Their home record of W12-D8-L3 reflects a side comfortable in front of their own supporters, while Tonda Eckert pointed towards Southampton's second half improvement in the first leg as an important positive ahead of the return match.
Middlesbrough arrive with strong confidence levels of their own. Kim Hellberg's side rank second in the Championship for xPTS across the last eight games with 14.04 while averaging 2.22 xG per game during that period.
The first leg was described by Hellberg as Middlesbrough's best performance since arriving in England. Boro dominated the opening half with 76% possession and 17 shots before Southampton improved after the break. With Southampton now expected to attack more aggressively at home, Middlesbrough should again find space on the counter.
Everything surrounding this second leg points towards goals.
How the bookies view it: Southampton narrow favourites
Southampton are priced at 7/5 in the match winner market, implying a 41.67% probability of victory. Middlesbrough are available at 2/1, implying 33.33%, while the draw sits at 13/5, implying 27.78%.
Over 2.5 goals is priced at 4/5, implying 55.56%, while both teams to score is available at 4/6, implying 60.00%. The underlying data and tactical setup both strongly support goals in this second leg.
Head to Head: A fixture that can go either way
Across seven meetings including the first leg, this fixture has averaged 2.14 goals per game with both teams scoring in four of the seven. The overall over 2.5 goals strike rate stands at three from seven, although the Championship meetings specifically have produced stronger attacking numbers.
The four Championship meetings before this tie averaged 2.75 goals per game with both teams scoring in three of them, although two finished 1-1. Middlesbrough's 4-0 victory at the Riverside in January 2026 and their 2-1 win in September 2023 both showed the level they can reach when games open up.
The first leg ended goalless, leaving the return match likely to be decided by small moments. One goal could completely change the tactical picture and force the other side to chase the game.
Players to watch: Whittaker main threat for Boro
Morgan Whittaker continues to produce strong shot volume numbers for Middlesbrough and the data supports him registering two or more attempts at St Mary's on Tuesday night.
Across 32 full starts this season he has averaged 3.36 shots per 90 minutes while producing two or more shots in 62.5% of those appearances. Away from home the numbers remain solid, with eight of his 16 full away starts producing at least two shots.
Recent form also strengthens the angle. Across his last 10 full starts he has registered 29 shots in total and reached the two shot mark in seven of those matches.
Whittaker has also produced strong numbers against Southampton specifically. Across three meetings this season he has recorded one, six and three shots. With Southampton expected to push forward at home chasing Wembley, Middlesbrough should again find space in transition and Whittaker is likely to remain heavily involved in the final third throughout.
Predicted line ups
Southampton 4-2-3-1: Peretz, Bree, Harwood Bellis, Wood, Manning, Jander, Downes, Fellows, Azaz, Scienza, Larin.
Middlesbrough 3-4-2-1: Brynn, Ayling, Fry, Malanda, Brittain, McGree, Morris, Targett, Whittaker, Conway, Strelec.
Anything else catch the eye?
Over 2.5 goals remains the standout angle because both the tactical setup and the recent attacking numbers from both sides strongly point towards chances at each end.
Middlesbrough's first leg performance highlighted the threat they carry. Boro generated 1.81 xG from 21 shots while producing five shots on target and 51 touches inside the Southampton penalty area. Southampton spent large parts of the game defending deep and now face the pressure of opening up more aggressively at home.
Across the last four matches Middlesbrough have averaged 2.09 xG per game and when combined with Southampton's xGA of 0.88, the projected Boro scoring output sits around 1.49 goals.
Southampton's attacking numbers also support goals. Across the last four games they have averaged 29.50 touches inside the opposition box per match, the highest figure in the Championship during that period. Their xG average of 1.84 per game combined with Middlesbrough's xGA of 1.04 produces a projected Southampton return around 1.44 goals.
Southampton also created chances in the first leg despite being second best overall. Harwood Bellis hit the crossbar while Cyle Larin also headed over from a strong position. The opportunities are there for both sides if the game opens up early. The combined goal projection from the recent numbers sits at 2.92.
While the overall head to head average of 2.14 goals across seven meetings introduces some caution, the tactical demands of this specific second leg should create a far more open contest than those historical averages suggest. Over 2.5 goals at 4/5 implies only a 55.56% probability and the underlying data still suggests that line is slightly underestimated by the market
