Crystal Palace are among a number of Premier League clubs interested in signing Chelsea's Conor Gallagher.
There are suggestions the England midfielder could leave Stamford Bridge this month - possibly on an initial loan - as Chelsea continue to add to their squad in January.
The Blues have already signed five new players this month and still want to strengthen in midfield and at right-back if they can.
Sky Sports News has been told a firm decision on whether Gallagher can leave Chelsea has not yet been made by the club.
Palace - who are actively looking to strengthen in midfield and at right-back themselves this month - had Gallagher on loan last season, when the 22-year-old scored eight goals in 39 games.
Gallagher's return would boost Patrick Vieira's side, who have struggled since the World Cup, losing four of their five matches - and failing to score in three of those.
In contrast to Chelsea, Palace are yet to strengthen in January
