Mark Warburton has warned former Doncaster winger Harry Forrester he will have to earn his place in the Rangers side after watching the Ibrox men rack up their biggest win of the season.
Forrester watched from the stands as the Light Blues ran riot with a 6-0 win at Dumbarton.
Veteran frontman Kenny Miller fired home a hat-trick while goals from Martyn Waghorn, Andy Halliday and James Tavernier completed a convincing win.
But winger Forrester, signed last week from Doncaster for an undisclosed fee, has been told he must prove he can cut it at Ibrox before he gets his chance.
Warburton - who is also expected to complete a deal for former Lech Poznan goalkeeper Maciej Gostomski next week - said: "A lot of work has been done already and a lot more work will be done because we said we'll strengthen and bring in players, and that's what we'll do.
"We want to get our business done early and hopefully we'll get a lot more done this week.
"But no player comes in and walks straight into the team.
"You saw the commitment of the players and whoever comes to the club has to justify their position in the team."
