Real Madrid striker Gonzalo Higuain is confident they can get at Manchester United's defence.
Higuain knows Sir Alex Ferguson's side pose a serious threat to their hopes of making the Champions League quarter-finals, but also believes the Spanish giants have the class and ability in their squad to really hurt their English counterparts.
He told the Bwin website: "They (United) are quite a compact team. They always make it to the knockout rounds in European competition and we're going to have to be on our toes.
"But we can do a lot of damage with individual quality and with counter-attacks, although we can't forget we need to have a solid defence, a winning mentality and team-spirit."
