Tottenham Hotspur manager Andre Villas-Boas has reportedly been shortlisted for a return to Portugal by former club Porto, who are monitoring his situation closely with a view to a sensational reunion.
Villas-Boas has come under increasing pressure at Spurs in recent weeks, thanks largely to a 6-0 humiliation at the hands of Manchester City.
That defeat saw some observers question his position, although Spurs have shown no signs of considering a change in management at this stage.
Porto are thought to be keeping a close eye on the possibility of persuading Villas-Boas to come back despite losing just one league game since January 2012, disappointed with an indifferent effort in this season's Champions League that has produced just one win in five matches.
Coach Daniel Fonseca needs to a positive result at Atletico Madrid next week to keep alive any fleeting hopes of qualification, and most likely his position at the Estadio Dragao.
A Porto club insider told The Sun that they would jump at the chance to make Villas-Boas their boss again, with the ex-Chelsea man fondly remembered after winning the treble in an unbeaten campaign two years ago.
He said: "Andre is held in such high regard the club will move heaven and earth to get him back. We hope he might welcome a return to his old stamping ground."
Spurs currently sit sixth in the Premier League, but did snap a four-game winless streak with victory in a London derby against Fulham on Wednesday night.
