Jermain Defoe will join Rangers on a permanent deal from Bournemouth this summer.
The 37-year-old striker, who moved to Ibrox on loan last January, has signed a pre-contract agreement for the 2020/21 season.
"When I first signed, as I've said many times, it was an easy decision because I have always known about the size of this football club and the history and the great players that have played for this club," said Defoe.
"I think for it to get all sorted and for me to secure my future here for another year is really special."
Defoe has scored 24 goals in 48 appearances for Rangers and his manager Steven Gerrard described the former England international as an "incredible professional".
"He is still contributing heavily," said Gerrard. "He is a major part of this group, this team and this squad and, hopefully, together we can go and share some success as I think he deserves that."
