Cardiff boss Neil Warnock dedicated his side's dramatic 2-1 win at Southampton to Emiliano Sala as Premier League clubs paid tribute to the forward.
Earlier this week, police confirmed that the 28-year-old £15m record Cardiff signing died in a plane crash.
“We wanted to do it for Emiliano and I'm really proud the lads have done him justice,” said Warnock after Cardiff scored an injury-time winner.
Players in games across the Premier League and EFL wore black armbands.
Sala's body was found and identified on Thursday and a minute's silence was held before the game at St Mary's Stadium with Cardiff fans wearing daffodils in memory of the Argentine.
“It's been a tough couple of weeks,” said Cardiff captain Sol Bamba. “I know Emiliano Sala was looking from up there so it's good to get the three points.”
Sala, 28, was travelling to Cardiff in a light aircraft piloted by David Ibbotson, which went missing over the English Channel on 21 January.
The striker was flying to join up with his new Cardiff team-mates for the first time.
The club has offered to pay for Sala's body to be repatriated to Argentina.
The body of the pilot is still missing and his family have launched a fundraising appeal to find his body.
