Cristiano Ronaldo set to deck out £28m retirement mansion with giant glass swimming pool and underwater walkway

CRISTIANO RONALDO will wash away his World Cup heartbreak by decking out his new Portuguese mega-mansion with a giant glass swimming pool with an underwater walkway, SunSport can reveal.

The Bond-villain style feature will enable former Man Utd ace Ron and girlfriend Georgina Rodriguez to look up at the water by using the underground corridor.

The new pool will go some way to help soothe Ronaldo‘s disappointment following Portugal‘s dismal display which saw them dumped out of the World Cup at the hands of Morocco.

The indoor pool will make-up a series of new features Ron has planned for his luxury retirement home in Quinta da Marinha near the coastal resort of Cascais on the Portuguese Riviera.

The 37-year-old star has also insisted on a huge master bedroom – measuring a massive 1,000 square feet, triple the normal size for a typical home in the area.

New details of the property Ron is expected to make his main residence in retirement emerge as it was claimed the cost of the project has rocketed to nearly £28million.

Earlier this year we revealed building costs had jumped from the £10m he set aside to £17m.

The rise was attributed to Ronaldo’s desire for perfection and the soaring price of materials.

Lisbon-based newspaper Novo is now reporting the cost of the mansion, due to be finished in June next year, has risen by another £11m.

The new price rise is thought to have been partly caused by the cost of relocating a posh golf clubhouse next to Cristiano’s super home.

The former Man Utd striker and his reps are said to be putting the “finishing touches” to a deal involving the relocation of the building and a car park at Oitavos Golf Club so he can have an unblocked view.

Ronaldo and his partner are already said to have picked four employees including a £4,800-a-month butler and chef for the new mansion.

The chef is described as a sushi specialist who will be given an area in the house specifically designed for the preparation of the Japanese delicacy.

Ronaldo and Georgina flew out of Qatar last weekend with their children on a private jet, with the 28-year-old model carrying one of her brood’s lifelike toy dolls in a black Hermes Birkin handbag.

The Spanish beauty wrote alongside a snap she posted on Instagram following Portugal’s shock quarter finals World Cup defeat to Portugal: “Going home. Thank you Qatar for these marvellous days and thank you to all the people who made it possible.”

Ronaldo’s Portuguese mansion, which is half an hour from Lisbon Airport, will add to an already-extensive property portfolio in his home country which already includes a seven-storey apartment block overlooking the Atlantic Ocean in Madeiran capital Funchal where his mum and older brother Hugo live, and two Lisbon apartments.
