Man City star Kyle Walker has highest estimated energy bill thanks to £3m mansion, pool, fish tank and waterfall

The Manchester City star's massive pad features six bedrooms, a football-themed games room and a hot-tub.

All in all, Walker pays roughly 15 TIMES the national average on his gas and electricity bills, according to the study.

Fortunately for the former Tottenham star, he earns a staggering £110,000 per week, meaning he can pay off his annual energy bill with almost a single day's work.

Walker's team-mate for club and country, John Stones, comes second in the list.

The Three Lions ace pays around £15,900 a year thanks to his sauna, cinema, leisure complex and heated indoor pool which costs £5,000 per year alone.

Manchester United team-mates Paul Pogba and David De Gea come in third and fourth respectively.

Pogba pays an estimated £14,300 per year on amenities such as his indoor football pitch with electronic scoreboard and LED lighting.

De Gea shells out roughly £14,100 annually thanks to his outdoor pool, gym, cinema, tennis court and electric security gates.

United and England star Jesse Lingard completes the top five at £14,000, with his indoor pool and cinema the biggest energy-guzzlers.

Harry Kane, Gareth Southgate, Marcus Rashford and Gareth Bale all pay over £10,000 per year for their energy, the study predicts.

And Jordan Pickford completes the top ten at £9,400 per year.

Among former stars, England's all-time top scorer Wayne Rooney leads the way with a £15,900 yearly bill thanks to his orangery, bar, TV room, snooker room, cinema and wine cellar.

That's more than David Beckham (£11,400) despite the Three Lions legend's plunge pool, steam room and sauna.
