Two Celtic players and one each from Aberdeen and Dundee are in the running for PFA Scotland's Scottish Premiership player of the year award.
Dutch defender Virgil van Dijk and Norway midfielder Stefan Johansen have helped Celtic lift the Scottish League Cup and lead the Premiership.
Irish striker Adam Rooney's 27 goals in all competitions have underpinned second-placed Aberdeen's strong season.
Dundee striker Greg Stewart is the sole Scot on the list after scoring 15.
It is the 25-year-old's first season in the top flight after leaving Cowdenbeath last summer and Stewart's side sit sixth after winning the Championship last summer.
The shortlist is made up of the four players who lead the voting among their fellow professionals, members of the Professional Footballers' Association.
