Chelsea have announced plans to expand Stamford Bridge into a 60,000 seater stadium at a rumoured cost of around £500m.
That's a lot of money, even for someone with pockets as deep as Roman Abramovich, but how does it compare to the sums forked out by other top flight clubs for their grounds?
To find out, the Trinity Mirror Data Unit have taken the building costs of new stadiums built in the post Taylor report era of the clubs in England's top two divisions and adjusted them for inflation.
Eclipsing Chelsea's suggested £500m budget are Arsenal.
When they started building the Emirates Stadium back in 2004 they spent a reported £390m.
However, when adjusted for inflation, that figure would have been £534.8m in today's money.
The Emirates though is the only stadium in our list of a similar size as the one proposed by Chelsea.
After the the Gunners come Manchester City, sort of.
When their ground was first built as an athletics stadium for the Commonwealth Games the construction cost was £112m, or £173.4m when adjusted for inflation.
Converting the ground for football though cost a reported £42m, which would be £61m today.
Altogether than the cost of the Etihad stadium could be said to have been £234.4m when adjusted for inflation. That's less than half the cost of Chelsea's proposed budget, but with a capacity prior to the recent expansion of around 46,000, it had 78 per cent as many seats.
Reading's Madejski stadium is the next most expensive new build at £81.3m in today's money.
Huddersfield's John Smith's Stadium comes next at £72.8m followed by Hull's KC Stadium (£62m), the Cardiff City Stadium (£59.5m) and Southampton's St Mary's Stadium (£48.1m).
The 90,000 seater Wembley Stadium, a possible temporary home for the Blues , cost a staggering £798m to build.
Work first started in 2002, and adjusting the cost for inflation from that date puts it at an eye-watering £1.16bn.
However, Wembley was being built for an awfully long time, and didn't open until 2007. If we adjust for inflation from that date the building cost is a slightly less staggering £989m.
By comparison to Wembley then, Chelsea seem like they might be getting something of a bargain at £500m.
