Rangers defender Nikola Katic aims to "help the club achieve something special" after signing a one-year contract extension until 2023.
Katic has made 41 appearances, scoring twice, since arriving on a four-year deal from Slaven Belupo in June 2018.
The 23-year-old Croatia international is keen to develop further at the Scottish Premiership leaders.
"It is a really good club for a young player, with this manager and a lot of good players," Katic said.
"That will definitely help me to grow every day and become a better person and a better player.
"We are in a really good position - the club is growing day by day, first in the league and hopefully we will keep that until the end.
"The relationship between the players is amazing, I have never seen something like that. We have like 30 players but I can't find anyone who is not good with me or I am not good with them."
Manager Steven Gerrard says the centre-back, who has one cap, fully deserves the contract extension and puts "his body on the line for this club".
"He is a player who comes in here and tries to improve every day," Gerrard said.
"The message to Niko now is that this is the start again, you reset yourself and keep trying to play at that consistent level because he has become a fans' favourite."
Katic has been a first-team mainstay this season, netting once in 12 appearances to help Rangers top the Premiership and reach the Europa League group stage for the second successive campaign.
