From Wikipedia: Scott Bain (born 22 November 1991) is a Scottish footballer who plays as a goalkeeper for Celtic. He has previously played for Aberdeen, Elgin City, Alloa Athletic and Dundee.
Bain joined Celtic on 31 January 2018, initially on loan from Dundee. Celtic needed another goalkeeper to provide competition for Dorus de Vries, following an injury to Craig Gordon. Bain made his first appearance for Celtic on 11 March, in a 3–2 win against Rangers, after de Vries suffered an injury in training.
With his contract with Dundee due to expire at the end of the 2017–18 season, Bain signed a four-year contract with Celtic in May 2018.
