After an impressive 3-0 win over Club Brugge in their opening Group G match, the Premier League champions will look to boost their hopes of making the knockout stages by beating the two-time champions of Europe.
Taggart told the Daily Star: “It will be electrifying – it's going to be like the Last Night of the Proms!
“After Tuesday everyone will be aware of what a Champions League night at the King Power Stadium means. Porto will certainly know they've been in the thick of it.
“That's what makes Leicester so special, the fans are included in everything by the owners.
“With their clappers, free pies and drinks they feel wanted. It's a cauldron all over the stadium.
“And that feeds to the players, who in turn give even more, chase every cause even harder."
