|6/1||Liverpool are 6/1 with William Hill to win the 2014-15 Premier League title|
Goal reported earlier this month that the Spanish club value the 21-year-old at €22 million (£17.6m).
Moreno made 29 La Liga appearances for Sevilla last season and narrowly missed out on a place in Spain’s World Cup squad.
“It's true that there is interest from several teams,” Castro told ABC.
“One of these teams is Liverpool, but there haven’t been any formal talks over his signing.
“We decide his price. If Alberto Moreno want to stay, he'll stay. If Liverpool pay his price, he'll leave.”
With Champions League football secured for the 2014-15 campaign, Rodgers is keen to add to his squad.
Rickie Lambert and Emre Can have already signed from Southampton and Bayer Leverkusen respectively, while interest in Adam Lallana remains.
