Arsenal line up £15m David Marshall bid?

Arsenal are reportedly lining up a £15m swoop for Cardiff City goalkeeper David Marshall.

The keeper impressed last season despite the Bluebirds' relegation from the Premier League, and the Gunners are looking to bring him to the Emirates this summer.

According to The Telegraph, the North Londoners see the Scotland international as an ideal addition to put pressure on Wojciech Szczesny for the number one jersey.

Marshall, who was named Cardiff's Player of the Season, only signed a new contract at the club in February.
