UNITED will look to put the slip-up against FC Copenhagen behind them when they travel to Celtic in the Champions League. Here is a look at the two sides ahead of the clash at Parkhead. FORM Celtic have taken advantage of the crises afflicting main domestic rivals Rangers and Hearts to cruise to a 15-point lead in the Bank of Scotland Premier League after the same number of games. They have been less consistent in Europe, where two home wins against FC Copenhagen and Benfica have been countered by a pair of away defeats to leave the Bhoys second in the group. Manchester United's serene progress to the knockout stages, which began with three straight wins, was shattered by a shock defeat at FC Copenhagen last time out when a weakened team struggled badly. Despite that, a point in Scotland would send the Red Devils though. PEDIGREE Celtic famously crashed out of the Champions League in the qualifying rounds last year after a humiliating 5-0 defeat in Bratislava against Artmedia proved too much to pull back. The greatest moment in the club's history remains the European Cup final of 1967, when the Lisbon Lions defeated Internazionale to become the first British winners of the trophy, in what remains their sole continental triumph. Manchester United, inspired by George Best and Bobby Charlton, won the same competition a year later when they saw off Eusebio's Benfica at Wembley and also clinched the rebranded Champions League in 1999 with a last-gasp win over Bayern Munich. Last year's campaign ended in ignominy when they finished bottom of their group to crash out at the first hurdle. MANAGERS Gordon Strachan recovered from the defeat to Artmedia to lead Celtic to the Bank of Scotland Premier League title last season and his job is secure with the Hoops odds-on to repeat the feat this time around. A win over United could take his side to the knock-out stages and would be seen as a major feather in his cap. Sir Alex Ferguson has silenced critics who have called for his resignation in recent seasons to lead United to the top of the Barclays Premiership with a side featuring some of the world's best young talent. After years of continental underachievement since their triumph seven years ago, the Scot is desperate to make amends this year. Tweet
