Christian Eriksen delivered another late winner as Spurs stunned Swansea with a 2-1 victory at the Liberty Stadium
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."
