Pompey's new owner Ali Al Faraj is said to be "very supportive" of plans to redevelop Fratton Park as soon as possible.
In a meeting with journalists at the club's ground this afternoon, chief executive Peter Storrie revealed Al Faraj's ambitions for Portsmouth to be a World Cup city in 2018 and to build a new training ground at Lee-on-the-Solent.
Mr Storrie said: "He (Al Faraj) has seen the plans and is very supportive of the plans and he's happy with them."
But plans for a dream stadium at Horsea Island are currently being shelved by Mr Al Faraj, he said.
"He would like to get a stadium quickly so therefore it's going to be Fratton because Horsea Island is going to take a long, long time and could go to public inquiries and God knows what else."
Mr Storrie said the club are in the process of revising plans for Fratton Park to incorporate retail and boost capacity to 36,000-seater capacity with the ability to extend to 45,000 with temporary seating in place for World Cup games, which is required by Fifa.
Storrie also said he held talks with Portsmouth City Council yesterday to discuss the 2018 World Cup bid and update them on the new ownership.
Lol so no new stadium for pompey after all!
