His pilot David Ibbotson's body is still missing.
Ghana striker Abdul Majeed Waris has bid his departed Nantes attacking partner Emiliano Sala.
Sala's body was recovered and formally identified earlier this week after a privately-funded search team found the plane's wreckage in the English Channel, off the coast of Alderney.
Sala´s family said on Friday that his body´s recovery and identification could help bring closure to "the most painful time of our life".
The Welsh club hoped Sala would help them avoid relegation from the world's most lucrative league this season after signing him from Nantes for a club record fee.
All Premier League and EFL players, including those at St Mary's, wore black armbands as a mark of respect for the recent tragedy and a minute's silence was impeccably observed before kick off.
In a later interview with French newspaper L'Equipe, Cardiff chairman Mehmet Dalman indicated that Nantes had sent an invoice for the first instalment, worth 6m euros (£5.27m).
Southampton said they would work with Hampshire police to identify individuals who made indecent gestures towards Cardiff supporters.
Southampton confirmed both supporters had been spoken to by Hampshire Police and meant to take "an extremely firm stance" over the incident.
"We offer our most heartfelt sympathies and condolences to the family of Emiliano", Cardiff City said in a statement on Thursday.
Argentine footballing idols Diego Maradona and Gabriel Batistuta also paid tribute to Sala, 28.
Their behaviour emerged in a video published to social media yesterday after Southampton lost 2-1 to Cardiff City at the St Mary's Stadium.
