Recently relegated London Irish are exploring their options over a possible return to London from their stadium in Reading.
The Exiles, who have been playing at the Madejski Stadium since 1998, were relegated from the Premiership following the end of the 2015/2016 season.
In a statement to the team's supporters, entitled "London Irish exploring options for a return to London", the club have revealed that talks with Brentford Football Club have taken place.
"Over the past decade London Irish has been linked with a number of possible stadium developments in London as the club kept the possibility of returning to its roots in the capital under consideration," read a statement.
"Numerous discussions have taken place with a variety of clubs over the last five years with a view to a possible ground share or joint stadium development.
"Brentford Football Club, who are well advanced with their own plans for a new 20,000 seat stadium in west London, is one of the clubs concerned. As an initial step in assessing this option, London Irish has today (August 15) begun formal discussions with the London Borough of Hounslow to explore the potential to play rugby at the new stadium.
"London Irish will continue to review all options and keep its supporters and stakeholders informed."
