Earlier this week, Hearts confirmed the signing of Barrie McKay, the former Rangers winger who had been released by Swansea City, while St Johnstone manager Callum Davidson has admitted it is a market he is looking at following an injury to midfielder Cammy MacPherson.
As long as players are released from their contracts or free agents before the close of the transfer window they remain available for clubs to sign.

There are individuals with Premier League experience in England or have proven themselves in Scotland already, while there are those who have performed well in Europe.
