Ki Sung-yueng was the unwitting match-winner as Swansea returned to winning ways at the expense of Hull
Swansea live updates
Swansea boss Garry Monk is unsure whether Michu will be returning to the club in January following reports in Italy that the Napoli loan signing was surplus to requirements at the Serie A club.
Michu, who scored 22 goals in his first campaign at Swansea before suffering an injury-hit season last term, has managed only three starts and five appearances for Napoli and failed to either complete 90 minutes or score for Rafael Benitez's side.
"I'm not sure contractually whether we could bring him back and we'd have to check fine lines before dealing with something like that," Monk said.
"I've not spoken to him recently but we'll see what the situation is and assess it from there."
Swansea have appealed against defender Federico Fernandez's red card in Tuesday night's Capital One Cup defeat to Liverpool.
The Argentinian was dismissed by referee Keith Stroud in stoppage time for a challenge on Philippe Coutinho and faces a three-match suspension.
A statement issued on the club's website read: "Swansea City can confirm that the club will be appealing the red card issued to defender Federico Fernandez against Liverpool last night.
"The club officially informed the Football Association by today's 1pm deadline.
"The FA will make a decision on the appeal ahead of Saturday's Barclays Premier League trip to Everton."
Swansea had led through Marvin Emnes' goal but Mario Balotelli equalised and, after Fernandez was dismissed, Dejan Lovren's header snatched a 2-1 win to send the Reds through to the quarter-finals.
Swansea City Supporters Trust has responded to the Barclays Premier League club after holding talks with potential investors by stating it does not believe there is a need for an ownership change.
The Trust owns more than 21 per cent of shares in the Swans.
Swansea revealed on Tuesday that they have spoken with potential investors who could buy a minority share interest in the club.
The Swans said in a statement they had spoken to "a number of parties" as they seek financing for planned expansion of the Liberty Stadium and a new training ground.
