Everton are the only team in the Premier League yet to concede a goal this season.
Although we are just two games into the new term, it's a solid start to the domestic campaign by Marco Silva's side with a 0-0 draw recorded away at Crystal Palace and a 1-0 win over Watford the most recent result.
The last time the Blues kept two consecutive clean sheets at the start of a top-flight season was in 1993/94 but the classy defensive foundation the Portuguese manager is building his team on goes way beyond the last two matches.
You have to go back to February 6 for the last time Everton conceded at Goodison Park - and that was against league champions Manchester City.
Liverpool, Chelsea, Arsenal, Manchester United, Burnley and Watford have all tried but failed to break through the Toffees' defensive line since then.
Meanwhile, away from home the Blues have conceded just five goals from open play in that same period - only City have conceded fewer.
Up next for Silva's men is an away trip on Friday night to face newly-promoted Aston Villa - and judging by Everton's recent defensive record the signs look good for them to record another clean sheet.
Should the Blues come away from Villa Park having conceded no goals it will be the first time since the 1912/13 season that they have kept three clean sheets in the opening three games of a top-flight campaign.
That's a record that has stood for more than 105 years but one that could easily be matched on Friday.
