Pompey are hoping rival fans from across the country will turn up at Fratton Park this weekend to show their solidarity.
The Fratton Park clash with Bristol City marks Fans Reunited 3.
When Plymouth Argyle faced extinction last year, a Fans Reunited day was organised where fans of all teams were encouraged to attend Home Park wearing their clubs’ colours.
Thousands of football fans attended, supporters of teams of all divisions, from the Premier League down to non-league.
In total, at least 50 different teams were represented at the match, with fans travelling from as far away as Falkirk to show their support.
Now Pompey Supporters’ Trust have joined forces with @Fansreunited on Twitter to send an invite to fans to visit Fratton Park on Saturday.
Trust spokesman Scott Mclachlan said: ‘At a time when football fans are often portrayed as hooligans in the media, this was an example of the good side of football.
‘It would be a great show of support from the football family if we saw fans from all over the UK come to the south coast and spend the afternoon enjoying a game of football and for 90 minutes forget football’s ills.’
Alternatively, supporters can donate to the Trust’s Pay4aPal scheme which aims to allow fans to buy tickets for local kids, young adults and supporters who can’t attend matches.
Donations can be made via the 12th Man website at http://www.pompeys12thman.co.uk/pay4apal.php or by a cheque made out to the Pompey Supporters’ Trust addressed to PST, Unit 2, 15 Rodney Road, Portsmouth, PO4 8TB.
