Manager Nigel Pearson has talked about addressing the elephant in the room of defending set-pieces in his press conferences, now it seems he has put a successful plan into action on the pitch.
After the New Year defending corners, in particular, emerged as a major Achilles heel with opponents sussing out a way to punish City's set-up.
It was the match against Barnsley last month that triggered a change in tactics when Poya Asbaghi's team scored two corners in 10 minutes to condemn the Robins to a 2-0 defeat.
After the game, when City conceded their 13th set-piece of the season, Asbaghi said: "Before this game our main focus was the set pieces because we knew that Bristol City is a team we could use spaces in a good way against. I am happy that focus paid off."
Pearson came under increasing pressure for his inability to stop his side from conceding set-pieces and prior to the West Brom draw, the following contest after Barnsley, he was asked on the challenge of improving that record in particular.
He responded: "Unfortunately, we don't have reliable markers so, we might have to find a different solution. Players are unable to stay with the men they are designated which has been a huge problem for us so unfortunately, we may have to look at a different solution and that's what we are working at, at the moment."
Since then, City have had to defend 17 corners in total, five against the Baggies and a further 12 against Scott Parker's Bournemouth at the weekend - successfully keeping their opponents at bay. Not only that, City even proved they can be a threat themselves from a corner when Rob Atkinson powered in a header at the opposite end of the pitch to give the visitors a surprise lead at the Vitality.
So what has Pearson done in particular over the previous two matches? The clearest way to show the difference is by revealing before and after pictures.
Birmingham's goal vs Bristol City (March 5)
City had four players in the six-yard box and a further four picking up their men in and around the penalty spot. On this occasion, Nico Gordon (pictured on the line of the six-yard box) scores with Antoine Semenyo losing his man.
Middlesbrough's goal vs Bristol City (February 19)
Another clear image to show how City were previously setting up from corners with three players taking up zonal positions inside the six-yard box and four marking their men around the penalty spot.
Matt Crooks (highlighted) scores when Tomas Kalas, his marker, is blocked off allowing the opponent to gain the extra yards and leverage himself to win the header.
These are just two examples of how City were setting up to defend corners prior to the Barnsley game, although a full rundown of five of the last corners conceded can be read here.
The cause
As you can see from both images above, the opponents had a player on the goalkeeper, not exactly uncommon, but in this scenario it proved crucial.
It forced the zonal defenders to retreat a couple of yards, meaning that when the delivery comes in, the likes of Chris Martin have more ground to make up to win the initial header - leaving the attacker to have an advantage.
Teams were also blocking off the runs from the man-marking players, allowing opposition players to lose their markers and cause havoc in the area.
The change
Bristol City vs West Brom (March 19)
As you can see from the above picture, the following game after Pearson said he was making a change to the way they defend corners, Han-Noah Massengo is the only City man towards the edge of the box.
City have put extra bodies both in the six-yard box and condensed the danger area by having an extra two players in between the penalty spot and six-yard area.
Again, when West Brom went short from a different corner to try their luck, it was a similar set-up with the Robins having extra bodies in the danger area. In total, they had 10 players back defending the corner with Nahki Wells left up top on his own.
Bristol City vs Bournemouth (April 2)
It was a similar tactic used at Bournemouth, with City putting an extra emphasis on putting players on the six-yard box. The Cherries set-up differently to West Brom having put men forward and leaving a lone player further back unmarked.
In this particular occasion, Bournemouth's players blocked off City's defenders and played the ball to Jefferson Lerma on the edge of the box to attack from deep although his header failed to trouble Dan Bentley.
Another example of how City's players have switched tactics from man-marking and instead put extra men in the condensed areas to provide an extra layer of security in front of Bentley.
Once again, including Jay Dasilva out in the wider position, City have 10 men in the ranks leaving Wells up front on his own.
What's next?
Pearson, a former defender himself, seems to have found a formula for now having successfully stopped the rot from corners but the proof will be in the pudding for the final six games of the season.
Saturday sees Peterborough come to Ashton Gate before a trip to Stoke, Sheffield United at home, Derby, Hull and Huddersfield when the curtain comes down on a rather uneventful season.
The final game of the season against the Terriers will prove to be the biggest test, with the play-off chasers scoring 16 goals from set-pieces this season - the joint-most in the league alongside Fulham.
Peterborough have only scored three, while Hull (4), Stoke (10), Derby (10) and Sheffield United (9) are all in the bottom half of the Championship table in regards to goals scored from set-pieces.
That in itself will be a telling test for Pearson's side and a real indication as to whether they can maintain the current record against sides not renowned for taking advantage of dead-ball situations.
