return stack.length;
Luke McCowan’s goal inside 30 seconds was irrelevant in the broader context of this tie. Stuttgart’s 4-1 canter in Glasgow a week earlier ensured that. Still, a game that had the whiff of irrelevance for Celtic delivered unexpected cheer. The statistics will show Stuttgart spent much of the evening camped in Celtic’s half – the hosts had 24 attempts at goal – but the Scottish champions played with a diligence and discipline that is worthy of huge credit. Sebastian Tounekti should even have delivered a second Celtic goal in the closing minutes. By then, Stuttgart were going through the motions.，详情可参考im钱包官方下载
