Former Premier League title winner Willian is exploring a return to the English top flight and Everton are believed to be among the teams considering a move for the striker.
The 36-year-old veteran attacker left England last summer following the expiry of his contract with Fulham and sealed a deal to join reigning UEFA Conference League champions Olympiacos on a one-year deal.
Willian was expected to bolster the club's attacking ranks, but his contract ended prematurely in December after making just 11 appearances for the club in all competitions.
Willian is now a free agent and does not appear to have any plans to retire yet, with four Premier League clubs understood to be contemplating a move for the winger.
Everton are among the teams considering an approach to the former Chelsea and Arsenal star, with newly appointed Toffees boss David Moyes hoping to welcome new reinforcements in January.
Willian's availability as a free agent, combined with his Premier League experience, makes him an attractive and profitable option for clubs near the bottom of the table.
Former Premier League champion Willian is exploring a return to the English top flight after his contract with Olympiacos was terminated.
Willian won the Premier League twice with Chelsea and could return to England.
His age also means that Willian probably wouldn't be in a position to command a huge salary.
The serial title winner is understood to be open to returning to England, where he previously spent his entire Premier League career playing and living in London.
In total he played 317 games in the Premier League and scored 47 goals, in addition to giving 46 assists.
Willian won the Premier League title with Chelsea in the 2014-15 and 2016-17 seasons, while he also won the FA Cup, League Cup and Europa League with the Blues.
While he had a significant impact at Stamford Bridge, the same cannot be said for Willian's time at Arsenal, for whom he struggled.

Everton manager David Moyes is expected to be backed by new signings in the January transfer window.
After returning to Brazil with Corinthians, Willian returned to the Premier League with Fulham, where he scored ten goals in 67 games.
He began his career at Corinthians and then played for Shakhtar Donetsk before joining Anzhi Makhachkala.
In 2013 he moved to Chelsea despite interest from Tottenham.
His brief time in Greece was marred by injuries. He failed to score in his few outings and only recorded one assist.
