Marshall was Cardiff’s stand-out performer in an otherwise torrid season for the Welsh club, which saw them return to the Championship after just one season in the Premier League.
The Scottish international, who won the Cardiff City player of the year award for his efforts this season, has also been linked with a move to Arsenal’s London rivals Tottenham Hotspur.
It is though Arsene Wenger would like to recruit the 29-year-old to increase the competition for the number one jersey at the Emirates. Polish keeper Wojciech Szczesny currently holds the vacancy, with Lukasz Fabianski providing the back-up. Spurs’ Hugo Lloris meanwhile has been rumoured to be heading out of White Hart Lane, hence the interest in Marshall.
A fee of around £8 million for Marshall has been branded around the British media, and is the kind of fee Cardiff are capable of attracting having only signed him on a new deal back in February.
Marshall commented prior to Cardiff’s relegation confirmation expressing his desire to play in the Premier League, but says he is more than happy with the prospect of staying in Wales.
"We worked really hard to get here and I've loved my first season in the Premier League," he said in the Daily Express.
"But being relegated wouldn't change anything. I've just signed a new contract in February so I'm more than committee to the club."
Marshall played in all but one of Cardiff’s Premier League games this season, and was the competitions most worked goalkeeper having made a staggering 153 saves. The Scot earned a ton of praise and recognition from players and pundits, and is widely expected to move on this summer.
With his place in the Scottish national team always under the watching eyes of manager Gordon Strachan, Marshall would also need first-team football assurances when moving to his next club, something Arsenal manager Arsene Wenger may not be able to provide.
