Former Chelsea defender Filipe Luis believes Leicester will face stiff opposition when they come up against Atletico Madrid, as both teams are fighters.
The Foxes will make the visit to Vicente Calderon after they were drawn against the Spanish side in the quarter-finals of the Champions League.
And Atletico defender Luis, who spent a season in England's top flight two years ago, believes the Premier League champions will come up against a side who are not too dissimilar to his own.
'There are similarities between Atletico and Leicester,' Luis told The Mirror.
