Newcastle eye history in Champions League clash with Barcelona
Howe's side will make only their second appearance in the Champions League last 16 when the Liga leaders arrive on Tyneside for a highly anticipated first leg clash.
For the first time since 2002-03, when they reached the second group phase, Newcastle are one of the 16 clubs remaining in a Champions League campaign.
But having eased past Azerbaijani underdogs Qarabag in the play-off round, Howe knows Newcastle will have to make a significant step up in class to stun Hansi Flick's star-studded team.
