Emiliano Sala expressed concerned about the plane on which he was travelling from Nantes to Cardiff.
The Piper Malibu plane carrying the 28-year-old Argentinian footballer and one other individual went missing over the English Channel on Monday night.
"I'm on a plane that looks like it's going to fall apart, and I'm leaving for Cardiff," Sala said in a WhatsApp audio message reported by the Argentine media.
"If in an hour and a half you have no news from me, I don't know if they will send people to look for me, because they will not find me, you know. Dad, I'm so scared."
On Tuesday afternoon, Guernsey Police said a number of floating objects had been spotted in the water but they were unable to confirm if the debris was from the plane carrying Sala.
It was added that if the plane had landed on the water, the chances of survival were "slim".
The search for the plane resumed at 7:30am on Wednesday morning.
"Two planes are taking off and will search a targeted area we believe has the highest likelihood of finding anything, based on review of the tides and weather since it went missing," said Guernsey Police.
"Coastal areas around Alderney and off-lying rocks and islands will also be searched from the air."

We are searching based on four possibilities:
1. They have landed elsewhere but not made contact.
2. They landed on water, have been picked up by a passing ship but not made contact
3. They landed on water and made it into the life raft we know was on board— Guernsey Police (@GuernseyPolice) January 23, 2019

4. The aircraft broke up on contact with the water, leaving them in the sea.
Our search area is prioritised on the life raft option.
