Manchester United manager Sir Alex Ferguson is happy to play against AS Roma again in the UEFA Champions League but believes it would be an intriguing tie. "It's amazing to think that we will have played Roma six times in a year," the Scot was quoted as saying on the club's website. "That makes it an intriguing tie because we know a lot about Roma, but they know a lot about us." The Red Devils thrashed the Romans last year 8-3 agg in the same stage and have been paired together in the group stage earlier this season. "I had a strong feeling that we would draw an English side," added Fergie. Four English teams reached the quarter finals this season as Chelsea will face Fenerbahce while Arsenal take on Liverpool. The 66-year old manager revealed that his biggest concern will be security matters. "During the game in Rome this season the security was much improved. But there will be even more fans travelling with us for this match." Last year's clash witnessed many violent incidents and they were many vitcims among the English supporters. The Italian police was also accused of over-reacting and being very brutal.
