Crystal Palace are eyeing Real Mallorca fullback Joan Sastre.
Marca says Palace are interested in signing 20-year-old Mallorca right-back Sastre.
However, it is understood that they face competition from Atletico Madrid and Premier League rivals Tottenham for the highly-rated youngster.
Both the Eagles and Spurs have sent scouts to watch the 20-year-old, and that both are considering a summer move for the defender, who has come through the ranks at Mallorca.
