The Costa Rican striker has seen his reputation skyrocket over the course of the past week after helping to fire his nation to the knockout phase of the World Cup at England’s expense.
His impressive displays have led to talk that he will be given a chance to prove himself at Arsenal after returning from a loan stint at Olympiakos, but Palace are already considering a move for his services.
Arsene Wenger has revealed that the 21-year-old will have the opportunity to impress him in pre-season, but the Eagles are confident that the prospect of gaining experience in the Premier League will appeal to both the Gunners and the player himself.
Campbell is yet to play a game for Arsenal since his 2011 arrival, with an initial work permit issue following his move from his homeland and much competition in his position at the club having seen him shipped out to Lorient, Real Betis and the Greek champions over the course of the past three years.
Newcastle are also rumoured to be watching the situation.
