Lucas Bergvall and Micky van de Ven’s post-match comments following Tottenham’s 1-0 win over Villarreal offer a window into the kind of mentality that Thomas Frank and his coaching staff have instilled in the squad.We are only a few games into the new season, but to say that Frank has put his imprint on this Spurs side would be an understatement.Tottenham have gone from a free-scoring side who were porous at the back under Ange Postecoglou to one that is almost impossible to score against.Spurs have kept four clean sheets in their last five matches, and even though Thomas Frank acknowledged that the Lilywhites were not at their best against Villarreal, he admitted that he is over the moon that his side did not concede yet again.Credit: @thefrederikkejensen / InstagramTottenham duo admit Thomas Frank has instilled a ‘clean sheet mentality’The comments made by two Spurs stars after the game reflect the change in how the players think compared to last season.Lucas Bergvall, who was the Man of the Match for the second consecutive game, said following the 1-0 win over Villarreal (via BBC Sport): “We talked a lot about ‘clean sheet mentality’ this year because we conceded a lot last year.”Centre-back Micky van de Ven echoed a similar sentiment, insisting that Tottenham take pride from the fact that they are hard to play against.The Dutchman said following the win over Villarreal: “I think we are a difficult team to play against, for sure. Structure-wise, we are standing really well, and we all know what to do, so we’re a difficult team to beat.”Tottenham do not have a soft underbelly any longerPostecoglou got a lot of things right at Spurs, and when things clicked, the football was electrifying to watch.However, even the Australians’ biggest supporters will not say that his Tottenham team were hard to play against.That is the biggest difference Frank has made, and it is clear already that no team will enjoy playing against the current Spurs side.The Danish coach is yet to get the balance completely right, but Frank is confident that Tottenham will click as an attacking force sooner rather than later.READ MORE: Tottenham receive seven-figure prize money just for beating Villarreal in Champions LeagueThe post Lucas Bergvall and Van de Ven reveal mentality Thomas Frank has instilled at Tottenham appeared first on Spurs Web.
