The best defending European clubs. Who are they?

Every coach dreams that his team would demonstrate iron defense in all matches and not concede goals. Which European teams from the strongest leagues of the Old Continent usually lock their opponents with uninterrupted padlocks this season? In first place - "Barcelona". Luis Enrique's students secured the title of Spanish champions when they defeated Madrid's "Atletico" 1-0 last weekend. It was the 23rd time this season that the Catalans kept "dry" gates in the local league. In second place - Munich's "Bayern". Josep Guardiola's trained German champions did not allow their opponents to score 21 times in 33 Bundesliga matches. The top rankings also include the champions of "Serie A" Turin's "Juventus" (19), "Monaco" (19), "Atletico" (18), and "Saint-Etienne" (18). English champions London's "Chelsea" and "Roma" share 7th-8th places (both with 17). The worst defense is demonstrated by "Cagliari" (3), "Getafe" (5), "Crystal Palace" and "Eintracht" (both with 6).
