Monday delivered a masterclass in defensive discipline, with eight teams across Brazil, Finland and a clutch of friendlies keeping their nets untouched while claiming maximum points.
The standout shut-out came in Turkey, where Eintracht Frankfurt dismantled Trabzonspor 3-0 in a friendly warm-up. Antalyaspor matched that scoreline against Zakho SC, also on Turkish soil, while a trio of European friendlies saw narrow 1-0 margins: Levante UD edging Al-Qadsiah, Jagiellonia Białystok seeing off ŁKS Łomża, and MKS Korona Kielce holding firm against Aris Limassol.
Brazil's Serie A tightens
In competitive action, Botafogo made the trip to Cruzeiro count with a slender 1-0 away win, while Remo doubled up on Vitória 2-0 to collect three Brasileirão points. Both results underline the fine margins at play in Brazil's top flight, where a single lapse can cost a game.
Finland stays stingy
Finland's Veikkausliiga added another clean sheet to the day's tally as Ilves beat FC Lahti 1-0, continuing a trend of tight domestic encounters in the Nordic league.
Across eight matches spanning friendlies and league fixtures, not one of these winning sides conceded. Whether it was defensive organisation, sharp goalkeeping or simple good fortune, Monday belonged to those who kept the door shut.
