One of the key punting puzzles for bettors to decipher is potential team news, not least where there is plenty of potential rotation to contend with. This can obviously have a significant impact on prices for the game, as well as presenting opportunities around popular markets such as first, last and anytime goalscorers.
Pep Guardiola's side are red-hot 1/8 (1.12) favourites to win the game with dabblebet who go 9/1 (10.0) on the draw. Bristol City, who knocked out Manchester United at Ashton Gate in the quarter finals in sensational style, are available at 18/1 (19.0) to shock the hosts and take a first leg advantage back to Ashton Gate.
While City are the lowest scorers left in the competition, having netted just three times thus far, the visitors are at the opposite end of that spectrum. Lee Johnson's side have notched 16 goals from 32 shots on target in their five games to date and have dumped out four Premier League sides en route to this stage.
Considering over 3.5 goals in this game is just 4/5 (1.80) with dabblebet, the bookmakers certainly expect another high-scoring clash and the goalscorer markets could provide some interesting angles for Tuesday's clash.
Sam has given us his predicted line-up for this game and expects Guardiola to name a changed, but relatively strong line-up as City chase the first domestic silerware of the season. Their impressive recent form, deep squad and kind draw compared to Chelsea's clash with Arsenal in the other semi-final means dabblebet make the Citizens just 8/15 (1.53) to lift the Carabao Cup at Wembley next month.
Predicted line up (4-3-3) - Bravo, Danilo, Stones, Mangala, Zinchenko; Fernandinho, Gundogan, De Bruyne; Bernardo Silva, Aguero, Sterling
While the above is a predicted line-up, as opposed to confirmed team news, it could provide some useful pointers in the goalscorer markets for those who are on the lookout for a wager.
It's no surprise that in the absence of Gabriel Jesus - who started against Leicester City in the quarter final - Sergio Aguero is the first goalscorer favourite, available at 2/1 (3.0) to score first and 4/11 (1.36) to find the net at anytime.
Raheem Sterling could be a popular alternative given his current hot streak in front of goal. The England international is 10/3 (4.33) to break the deadlock or 7/10 (1.70) to score during the 90 minutes. With 14 goals in the Premier League thus far this season, should Sterling start Tuesday's game, he could be a solid option to net his first Carabao Cup goal of the campaign.
One man who has already been on the scoresheet in this competition is Bernardo Silva, who was on target with the opener at the King Power Stadium last time out.
The 23-year-old has only started six league games since arriving at the Etihad but is a perfect three from three in terms of starts in this competition and could be in line for another prominent role. The former Monaco man is 6/5 (2.20) to score and 11/2 (6.50) to hit the first goal of the game. Kevin De Bruyne has netted six times in the Premier League so far and the Belgium international is a 6/4 (2.50) shot in the anytime scorer market.
Both teams to score is 23/20 (2.15) which shows how much of an uphill battle the bookmakers believe the Robins have on their hands.
On the Bristol City side, Matt Taylor has been involved in four League Cup goals (two goals, two assists) this season and is 15/4 (4.75) to score during the 90 minutes while Bobby Reid, who is the club's leading scorer in the Championship with 12 goals this campaign, is 12/1 (13.0) to break the deadlock and 14/5 (3.80) anytime.
