Visiting Cardiff fans at Arsenal's Emirates stadium unveiled a banner reading: "We never saw you play and never saw you score but Emiliano our lovely bluebird we will love you forever more".
The search and rescue team are due to commence a fresh search this weekend due to hard weather conditions expected over the coming days.
The light aircraft carrying 28-year-old Sala and pilot David Ibbotson disappeared on January 21 after losing contact with Jersey air traffic control on its journey from Nantes to Cardiff.
The initial ending of formal efforts to find Sala and the pilot prompted impassioned calls from the player's family and fellow professionals including Argentine star Lionel Messi for the search to continue.
In the away end, fans held aloft a banner which proclaimed: "We never saw you play and never saw you score, but Emiliano our handsome Bluebird we will love you forever more".
"What's gone on this week is unprecedented, really. You've not really wanted to get out of bed because everything was really miserable", Cardiff Manager Neil Warnock said (via ESPN). "I know we've lost a game of football but there are more important things".
Solskjaer proud of United response after sluggish start
Solskjaer handed Andreas Pereira his first Premier League start since August and it was the Brazilian who was robbed of the ball in midfield in the buildup to Burnley's first goal.
Reflecting on the heartbreaking situation, Bamba told BBC Sport Wales: "It is very hard to even describe how the players are feeling". It is very unusual, a big tragedy.
"And I think some of the lads do, they need to get it out".
In part, players were confronting their fear of flying.
Mr Mearns said Sala's family is "looking at this as a missing person, a missing plane and until they are satisfied, that's the mode that we are in". "It was that deep".
