Celtic through but Mjallby ruled out for Stuttgart
The Sweden international defender looked shaky at times on his return to the side after a thigh injury picked up against Dundee United on January 29. His team-mates still managed a less-than-vintage 3-0 victory over St Johnstone in the Tennent’s Scottish Cup fourth round tie at Parkhead.
The result keeps alive their quadruple trophy dream, but Mjallby is unlikely to stay in the side for the return leg in Germany this week.
