Everton are exploring the free-agent market for a new striker after failing to complete a forward signing before the transfer deadline, with veteran marksman Jamie Vardy emerging as one option under consideration.
The 39-year-old is currently without a club having departed Italian side Cremonese, and reports suggest David Moyes' side see him as a potential short-term solution to bolster their attacking options. Vardy, who made his name with a prolific spell at Leicester City including their remarkable Premier League title triumph, remains a free agent as clubs assess whether he can still contribute at the top level.
Alongside Vardy, Everton are also said to be looking at another experienced frontman in Anthony Martial. The 30-year-old Frenchman left Mexican club Monterrey and is similarly available on a free transfer. Martial, once a highly-rated young talent at Manchester United, could offer Moyes another proven option as the club looks to strengthen its forward line outside the traditional transfer window.
Elsewhere in the market, Ivory Coast winger Wilfried Zaha, 33, has been linked with a move to AC Milan, who are reportedly weighing him up as a free-agent addition to add depth on the left flank of their attack.
At Chelsea, teenage Brazilian playmaker Estevao Willian is reportedly growing anxious over his first-team opportunities under new head coach Xabi Alonso. The 19-year-old could reconsider his future in January, depending on how much game time he receives between now and the turn of the year.
In other developments, Arsenal have safeguarded their long-term interests in Ethan Nwaneri by inserting a recall option into his season-long loan move to Borussia Dortmund. The 19-year-old England Under-21 international could be brought back to the Emirates Stadium in January should the north London club require reinforcements.
Sunderland are facing the prospect of losing winger Chemsdine Talbi, with the 21-year-old Morocco international currently in discussions with Saudi Pro League side Al-Ittihad. Turkish giants Fenerbahce and Galatasaray have also been credited with interest in the player, setting up potential competition for his signature.
Meanwhile, in an unusual twist away from Europe's traditional leagues, former Manchester United and England winger Jadon Sancho, 26, is reportedly a target for Arabian Falcons, a club competing in the United Arab Emirates second tier managed by former Newcastle midfielder Jonjo Shelvey.
Finally, Inter Milan will be relieved to have held onto prized striker Lautaro Martinez despite reported interest from Barcelona. The Argentina international addressed the speculation directly, expressing gratitude for the attention while affirming his commitment to the Serie A club.
"It was an honour to have attracted interest from Barcelona but I wanted to stay at Inter Milan," Martinez said, putting to rest any doubts over his immediate future at the San Siro.
As clubs across Europe continue to assess their squads following the closure of the summer window, the free-agent market and loan arrangements look set to remain active talking points in the coming weeks, particularly for sides like Everton searching for late reinforcements to their attacking ranks.
