Garner made a rather slow start to his Rangers career, but he has shown his quality in recent weeks.
The former Preston North End man has earned widespread praise for his recent performances, and he seems to have established himself as Rangers’ main striker.
And Warburton said: “The quality on top, they enjoy, but they want to make sure they see the effort, and Joe Garner gives you 100% every time he pulls a jersey on.
“The fans are seeing that now – but his quality is apparent. His clever movement, his timing of his leaps, his tackles and his runs – he is a top class professional, and we are delighted to have him on board.”
Garner’s goalscoring record for Rangers is still largely unremarkable, as he has only notched three times in 15 appearances.
However, the 28-year-old’s work rate has earned him a great amount of credit with the Ibrox crowd.
Garner was given a standing ovation when he was substituted off during Rangers’ latest match, which came against Hearts last weekend.
Garner is now expected to retain his place in Warburton’s side’s starting line-up for the foreseeable future, with the Glasgow side next in action against Hamilton on Friday evening.
