Fratton Park North Stand sponsors The Car Finance Company and The World Of Cars are hosting the event at the auto dealer’s centre in Shawcross Industrial Park, Hilsea.
Visitors will be able to chat with Portsmouth FC striker Ryan Taylor and goalkeeper Michael Poke and have photos taken with them.
The World Of Cars general manager Kevin Fox said it would be a fun, family-focussed event featuring a contest to keep a ball in the air the longest and a goal-scoring competition using a portable goal.
There will also be a hot-dog vendor and drinks available for visitors.
‘It should be lots of fun,’ Mr Fox said.
Michael Hollands of the Car Finance Company said the event marked the renewal of the sponsorship deal with Fratton Park.
‘We are proud to be the sponsors of the North Stand again,’ he said.
‘This will be a great chance for the Portsmouth fans to come and meet some of their favourite players.’
Anyone who buys a car at the event will get extra bonuses including lunch with the players and a signed shirt and football. The celebration will run from 5pm to 8pm.
