As we prepare for a busy January transfer window, Premier League clubs including Arsenal, Liverpool and Chelsea will be acutely aware of a number of big players' contract situations.
While Jurgen Klopp's Reds and Graham Potter's Blues have stars approaching the final few months of their current deals, Mikel Arteta's Gunners have the benefit of eyeing up those whose contracts elsewhere are close to expiry. Those with contracts expiring in June will be free to speak to potential suitors in the coming weeks, while some may choose to cash in rather than risk losing players for nothing.
With clubs from Europe's top leagues returning after the World Cup with varying priorities, we could see some more big names on the move either next month or over the summer. Those approaching the end of their current deals include superstars approaching the twilight of their careers as well as those nearing their peak years in the game.
