The Gers have been left wounded by two 4-0 defeats on the bounce against Celtic and then Ajax with an expectant Ibrox hoping to see the side bounce back this week.
Napoli represent challenging opposition for the Ibrox side after an explosive start to the season sees them topping Serie A and blowing Liverpool away 4-1 in their Champions League opener.
After Liverpool defeated Ajax 2-1, Rangers are now the only side without points on the board in Group A and ex-Rangers striker Marco Negri believes the Gers support have the power to inspire an upset against Napoli.
Marco Negri: “Napoli facing “dangerous” Rangers
Speaking to Italian outlet Tutto Mercato Web, the Italian former striker claims that Napoli face a “wounded Rangers” but insists the Ibrox club are “still a very dangerous animal”.
“The Champions League at Rangers has been missing for a long time, there is a frantic wait,” said Marco Negri.
“After 10 years of ups and downs, the club has returned to the highest levels and managed to be among the best clubs in Europe.
“Napoli must know well: the 50 thousand Scottish fans will be heard loudly, especially given the difficult moment experienced by Rangers in this start of the season.
“After the passage of the preliminary round with PSV they have exhausted their nervous energy a little, but against Napoli it will be all different.
“The Azzurri will trigger the Rangers’ motivations to the maximum. And then the nights of Champions at Ibrox are different, they are special.
“At home the club then built its path towards the final of the last Europa League. Napoli will face a wounded Rangers, but still a very dangerous animal.”
The ex-Rangers striker has also been speaking about the high-profile injury to Nigerian international Victor Osimhen.
Napoli will be without their £82m forward for the clash with Mexican winger Hirving Lozano also ruled out.
Negri has warned back-up striker Giovanni Simeone that the Ibrox atmosphere takes some getting used to and if he can’t adapt he can expected his legs to “tremble”.
“It is a huge loss (Osimhen),” said Marco Negri.
“For me he is a striker 2.0, the evolution of the bomber of the past. He works alone, he gives you many solutions. And the defensive line of the opponents is always worrying.
“It will certainly be a huge loss for Spalletti, even if he has many alternatives ahead.
“There is Simeone who will play as a starter and I hope he will put aside the thrill he saw against Liverpool, otherwise Ibrox will make your legs tremble”.
Meanwhile, one Ibrox star is set to come into the team against Napoli after yet another injury to an Ibrox first-teamer.
