Stoke City are facing a challenge to hold on to striker Tyrese Campbell, with the England U20 international attracting interest from a number of top-flight clubs.
Crystal Palace, Wolves, Celtic and Rangers are among those to have monitored the 20-year-old, whose contract expires at the end of this season.
The son of former Arsenal and Everton striker Kevin, Campbell has scored three goals in his last three appearances for Stoke as a recent upturn in form under Michael O'Neill has pulled the club out of the relegation zone.
Stoke remain hopeful that assurances over playing time can persuade Campbell to sign a new deal.
Campbell, who has impressed within the England set-up and scored in both his appearances for Paul Simpson's side, turned down a professional contract with Manchester City in 2016 to join Stoke with a £1.75m fee set at an FA tribunal.
A prolific talent at youth level, he scored 49 goals in a season with City's U16s before making his Premier League debut under Paul Lambert at Stoke in February 2018.
Campbell spent the second half of last season on loan at Shrewsbury Town, scoring five goals in 13 starts.
