The Evening Gazette says Manchester City, Wigan, West Ham, Middlesbrough and Portsmouth watched the winger score twice for Levante in the 2-0 win over Racing Santander.
Riga said: “It is certain for a month now that there have been several clubs from England looking at me and that want to sign me.
“But I have not been saying anything because the first thing was to save Levante.
“Now that we are safe in La Liga I can say yes, the interest exists and I know that they are going to make an offer soon.
“I just want the best thing for everyone, and I cannot deny that I would like to play in England.
“One of my dreams as a footballer was to be in the Premier League.
“I could have gone before I joined Levante but I thought it was best to come to Spain.
“Now after two years here, I have fulfilled the objectives that I gave myself and now I would like to play in England.
“I came for free to Levante and I believe I have proved myself as they expected.
“Now the offers have arrived and they will duplicate my pay and I just believe this is the best thing, especially for a player who cost the club nothing.”
