Nice 1-4 Rangers: Have your say
Vaclav Cerny, so often Rangers' saviour this season, watched his deflected strike wrong-foot goalkeeper Marcin Bulka, before Mohamed Diomande audaciously flicked in a second within three minutes
The Ivory Coast international capitalised on some horrendous defending by the much-changed hosts, and another comical error from Nice gifted Rangers a third before the break.
Hamza Igamane, who inexplicably squandered a chance earlier, pounced on a dreadful blind back-pass to spark bedlam in the away end.
In truth, it was a night where everything went right for Rangers.
The disastrous defending carried on into the second half as Igamane intercepted a poor pass from Issiaga Camara before nutmegging the defender and rolling in a fantastic fourth.
On an otherwise chastening night for the hosts, Bouanani curled in a classy free-kick late on as some sort of consolation.
