Sevilla boss Julen Lopetegui has hailed Chelsea as the Premier League's best attacking team ahead of Wednesday's meeting between the sides in Spain.
Lopetegui claimed before his team's Group E opener at Stamford Bridge in October that Frank Lampard's Blues were among the favourites for the Champions League title, and he has not changed his mind.
Both sides have already secured qualification for the knockout stage and head into the encounter battling to top the pool, leaving Lopetegui excited by a stern examination of his team's credentials.
'It's a huge and exciting challenge against a team who could win the Champions League,' the former Spain coach said.
