#4 Villarreal
After losing talented midfielder Rodri who will join Atletico Madrid next season for €20m, El Submarino Amarillo (The Yellow Submarine) may lose another of their talented Spanish youngsters as reports have it that AC Milan are keen on signing left-footed winger Samu Castillejo.
According to Marca, the Rossoneri are concerned about Liverpool's pursuit of ex-Red Suso and should Jurgen Klopp's side make a good enough bid, the Milanese will turn to the 23-year-old ex-Malaga star.
Villarreal is also said to be in the race for 24-year-old Ivorian central defender Wilfred Kanon who plays for Eredivisie side Ado Den Haag.
The team is hoping that their previous experience with Kanon's countryman Eric Bailly will convince the defender that the Estadio de la Ceramica will offer him a better chance at stardom.
The deal could cost Villarreal a cut-price sum of £2m.
