Reigning champions, Barcelona, were frozen out of tonight's Champions League clash with Russian champions, Rubin Kazan and could only manage a 0-0 draw.

With just five points from four games so far in the competition and languishing down in third place in Group F, qualification for the knock-out round of the competition is starting to look less of a foregone conclusion for Pep Guardiola's star-studded side.

Zlatan Ibrahimovic came closest to forcing a goal, hitting the post after just two minutes, but Rubin held on to take their points tally against the Catalan giants to four following their shock success at Camp Nou in the first leg.

Elsewhere, Sevilla allowed their 100 per cent record at this stage of the competition to slip after they were held 1-1 at home by Stuttgart.

Jesus Navas appeared to have preserved the Spaniards' perfect run, after he hit the back of the net after 14 minutes, but Zdravko Kuzmanovic snatched an equaliser for the Germans 11 minutes from time.

Despite this minor slip-up, Sevilla sit at the top of their group with ten points and are already sure of a place in the last 16, where they will join Chelsea, Manchester United and Arsenal who have all made sure of their passage through to the next round. 

Liverpool and Rangers' hopes of qualifying however are disappearing fast.  Rangers have managed just two points from four games and Liverpool's 1-1 draw in Lyon tonight means that they lie in third place with only four points, five points adrift of second-place Fiorentina.
