David Marshall deserves to be first-choice goalkeeper for Scotland despite the claims of Allan McGregor and Craig Gordon, believes ex-keeper Alan Rough.
Marshall, who has just joined Hull City from Cardiff City, is in line to start Sunday's World Cup qualifier in Malta.
The 31-year-old played in nine of Scotland's 10 Euro 2016 qualifiers and their two end-of-season friendlies.
"For me, David is the number one and he should remain the number one," said Rough, who won 53 Scotland caps.
"I'm a great believer when you are number one, unless you do something wrong, you should remain number one.
