The 23-year-old joined Liverpool in 2013 under Brendan Rodgers has found first-team chances hard to come by.
Alberto, who joined the Reds from Sevilla after a stint with Barcelona B, has spent the last two seasons on loan with Malaga and Deportivo La Coruna respectively.
Derby County and Villa are a little further back at 8/1 to sign the Liverpool playmaker, along with Bristol City.
The Echo reported that the Anfield club were looking for some £6 million, which might deter Derby but Wolves - recently taken over by Fosun International - and Aston Villa could stump up the money needed to prise him from Merseyside.
Villa, relegated from the Premier League last season and also under new ownership, kick off their Championship season away to Sheffield Wednesday on Sunday, while Wolves visit Rotheram United on Saturday.
