Rangers centre back Rob Kiernan has told The Scottish Sun that manager Mark Warburton demanded more from his players after the 1-0 win over Hibernian.
Warburton was appointed Rangers boss earlier this summer after leaving Brentford, and his reign at Ibrox so far has gone almost perfectly.
With six wins from six games, Rangers are in fine form, and many of the summer signings brought in by Warburton have hit the ground running, including defender Kiernan.
Signed from Wigan earlier this summer, Kiernan reunited with his former Watford coach Warburton, and has instantly struck up a partnership with fellow new arrival Danny Wilson in the heart of the Rangers defence.
The duo started Sunday's big match against Hibernian, a game which Rangers won 1-0 thanks to a superb strike from another new signing, James Tavernier.
The result kept up Warburton's 100% record so far, but Kiernan has told The Scottish Sun that his boss wasn't totally pleased with the performance, sending a message to his squad after the game.
"After the game the manager said there was a lot more to come from us," said Kiernan. "It wasn’t our greatest performance but we got the job done and took three points," he added.
It's still early days for Warburton at Rangers, and whilst his side will grow in confidence under him as the season progresses, six wins from six is no easy feat.
Warburton rightly wants his side to continue to improve having failed to hit top form against Hibernian, but if they can beat their main title rivals even on an off day, this should be a great season for Rangers.
