Gers face Celtic in what is a highly-anticipated Old Firm semi-final Scottish Cup clash at Hampden Park.
Following their division one title win and ensuing Petrofac Training Cup success, the pressure is seemingly off Rangers heading in to the derby and they can enjoy the challenge as underdogs.
Celtic, however, are the current best team in Scotland and with every defeat or uninspiring performance boss Deila has come in for criticism, especially considering the club’s poor form in Europe.
Warburton, however, has defended Deila and understands the difficulties in managing expectations.
“I find some of the criticism that he receives quite staggering. They are top of the league and have got to a semi-final. I understand some comments about Europe, but I think he has done a tremendous job in that respect,” Warburton told Herald Scotland.
“After nearly a year [in Scottish football], I think I have come to understand what is involved and how it works. I’m sure Ronny knows it as well. He has been here longer than I have.”
“But I think some of it has been inappropriate. I don’t think it is warranted when he is top of the league and doing what he is doing. I can’t comment on Celtic fans and their view. But I know the job he is doing.”
The Old Firm derby this weekend will be the first between the two since last season’s League Cup semi-final encounter - a match which the Hoops ran out comfortable 2-0 winners.
Rangers have improved since then, and they will be hopeful of giving Celtic a much sterner test.
Many have speculated whether a defeat will see Deila lose his job at Celtic Park, but the Norwegian deserves more time and the challenge of Rangers next season could actually help his cause.
