The Dutchman was sacked by Manchester United a year ago, but is open to a comeback in England.
The former United chief will be back at the club today for the Michael Carrick testimonial, his first return to Old Trafford since his exit.
And that could be the prelude to a more permanent return with Southampton – and possibly Crystal Palace – interested.
Van Gaal has taken a year off to recharge his batteries after his Old Trafford exit and sources close to the 65-year-old claim there have been low-key approaches to sound out his interest.
Saints are ready to ditch Claude Puel after an underwhelming season at St Mary’s – and it’s believed Palace have also discussed the Dutchman.
Southampton have already had one Dutchman in charge recently – Ronald Koeman – and Saints owners are impressed with Van Gaal’s track record.
Van Gaal was stung by his sacking just hours after winning the FA Cup against Crystal Palace in May last year.
The former Holland gaffer felt he he was harshly treated and has told friends he would still listen to offers from English clubs.
Palace chairman Steve Parish, meanwhile, is taking his time assessing a hit list of candidates after Sam Allardyce rocked the Eagles by retiring after guiding the club to safety in his first season at Selhurst Park.
Sean Dyche, Chris Coleman, Brendan Rodgers, Roberto Mancini and Claudio Ranieri have all been on Palace’s radar – with Van Gaal also thought to have been discussed by Parrish and his board.
