Pompey have stopped short of emphatically declaring their commitment to Fratton Park.
But Mark Catlin has labelled the option to stay as a ‘dream scenario’.
The much-vaunted stadium masterplan has yet to be released following Tornante’s thorough year-long research.
Yet the message continually coming out of Fratton Park is that the Blues will remain.
That is, according to Catlin, unless a ‘no-brainer’ alternative emerges.
He said: ‘The owners have undertaken a year of comprehensive studies of different options available, including staying at Fratton Park.
‘They are minded to stay at Fratton, but we don’t want to lock ourselves in, we’re keeping all options open.
‘It has been clear from the start the owners want to stay. Michael (Eisner) has consistently said it, Andy (Redman) has consistently said it, Eric (Eisner) has consistently said it. In a dream scenario they would like to stay at Fratton Park.
‘That is and continues to remain the case – while keeping all other options on the table.
‘It can’t be set in stone, in business things change.
‘While they are minded to stay at Fratton Park, if tomorrow something becomes available that commercially and financially made it a no-brainer then they don’t want to be handcuffed by a statement about definitely staying.
‘As an ownership group that listens to the fanbase, there’s a general feeling the board would like to stay at Fratton Park.
‘But we can never discount that if a slam dunk opportunity came to move elsewhere then it would be seriously looked at.’
Tornante’s desire to retain the Fratton atmosphere has been pivotal.
But Catlin also believes there’s a lack of land alternatives for a new stadium.
He added: ‘There are no real areas which would give us everything we need in regards of infrastructure and transport links.
‘There are not even hard options out there, let alone easy options. There are just ones that could end up tied in red tape for years and years.
‘If you go off the island here are more options, but then you start to lose the heart and soul of the club, which isn’t something Michael and the directors want.
‘We are minded to stay at Fratton Park, but it’s something under constant review.’
