It has been reported by the British newspaper that Everton want to recruit the goalkeeper as a replacement for Tim Howard.
Howard has been on the books of the Merseyside outfit for almost a decade. The goalkeeper initially joined the Toffees on loan from Manchester United for the 2006-07 season and thereafter made the move permanent, as reported by BBC Sport at the time.
The USA international is the first-choice goalkeeper at the Toffees at the moment, but the 36-year-old has made mistakes this season and fans are not happy with his performance (click here to read more).
Marshall has been on the books of Cardiff since 2009 and has a contract until June 2018.
“Marshall is under contract at Cardiff until the summer of 2018, having signed a four-and-a-half-year deal in February 2014,” added the report in The Mirror. “However, he has Premier League ambitions, something the Welsh club cannot currently match.”
Everton are 11th in the Premier League table at the moment with 26 points from 19 matches, as many as nine points behind fourth-placed Tottenham Hotspur.
Meanwhile, Cardiff currently find themselves 10th in the Championship table with 34 points from 24 games, six points behind Ipswich Town, who are sixth and occupy the final playoff spot.
