Derek McInnes has backed Thelo Aasgaard to reach his "huge potential" at Ibrox.
The 24-year-old midfielder returned early from his World Cup break to feature in Rangers' 2-1 victory over St Etienne, scoring a decisive penalty.
Despite a £5 million move from Luton last summer, Aasgaard struggled to make a consistent impact in his debut season.
However, McInnes is optimistic that the Norwegian can improve under his guidance. McInnes said: "I think I can [get more out of him], but also Thelo has got to get that from himself as well.
"He’s so smooth and he looks every part a footballer, the size, the technique, the speed. We just need to try and get him at his best week in, week out."
The manager highlighted inconsistency as a key issue for Aasgaard and other players last season.
He added: "We need to try and get Thelo and others a wee bit more consistent, but sometimes, being young players and with the size of the club and the demand, you’ve got to work through that."

McInnes was disappointed with the team's first-half performance, describing them as "really quiet" and "feeling sorry for ourselves".
He emphasised the need for unity and resilience, saying: "We need to make sure that we galvanise each other. Football is not always sunshine and rainbows."
At the end of last season, chairman Andrew Cavenagh expressed hope that a refreshed leadership group and stronger spine can give players like Aasgaard the platform to consistently demonstrate their abilities.
McInnes echoed this sentiment, saying: "Players like Thelo and others need to fight through that and show their capabilities.
"Sometimes, in a technical game, these games are a bit easier to show, and other times, when you’re not getting it all your own way, you’re going to have to dig deep.
"Thelo, without question, has got huge potential and it’s up to him and us to get it out of him."
