Porto - Porto's four fantastic goals showed the gulf in class with their Champions League victims Basel, who were outgunned in every department in their last-16 second leg on Tuesday.
Julen Lopetegui's side were in scintillating form to beat their sorry Swiss opponents 4-0 on the night, with excellent long-range strikes, to complete a 5-1 aggregate victory.
Porto, who along with Chelsea are the only unbeaten sides still in the competition, showed they will be an unwelcome draw for the more-fancied teams left in the last eight.
