According to Gullit, the main issue lies in the team's lack of cohesion. He thinks that the players do not work together as a unit, with each individual making their own decisions on the pitch. This, in turn, leads to a breakdown in the team's defensive structure. Gullit has praised Bart Verbruggen as a "certainty" in goal, but has been critical of the rest of the defence. He believes that Jurriën Timber makes too many mistakes in defensive situations, while Denzel Dumfries is vulnerable in defence despite being a threat going forward. Virgil van Dijk is seen as a player who often avoids duels, and Gullit has expressed doubts about Jan Paul van Hecke's abilities. Micky van de Ven is a player that Gullit has praised in the past, but he believes that the Tottenham Hotspur defender tries too hard and often gets injured as a result.
