Tottenham have conceded just one goal so far this season under Thomas Frank
Outscoring the opposition was the mentality at Tottenham last season but now the focus is on keeping out goals at the other end of the pitch.
Tuesday's 1-0 win against Villarreal in Spurs' Champions League opener was the fourth clean sheet they had kept in five games so far this season under Thomas Frank.
In contrast, they had kept just one at the same stage of last season, when the more attack-minded Ange Postecoglou was in charge.
"We talked a lot about 'clean sheet mentality' this year because we conceded a lot last year," Tottenham midfielder Lucas Bergvall told Amazon Prime.
