Despite thrashing Brondby 6-2 on their trip to Copenhagen, Manchester United manager Alex Ferguson has urged his side not to underestimate the Danish champions.

"You only have to look at Brondby's record in Europe to see they beat Karlsruhe 5-0 in Germany. Any mistake now could cost us dearly."

Phil Neville and Nicky Butt are fit and Denis Irwin is likely to replace Wes Brown. Arsenal, away to Dynamo Kiev in Group E, are without Dennis Bergkamp, Marc Overmars and Tony Adams. Steve Bould will replace Adams, while Christopher Wreh and either Stephen Hughes or Luis Boa Morte are likely to start.
