Valentijn Driessen has been particularly critical of Filip Kostic following PSV’s 2-1 Champions League defeat to Club Brugge, arguing that the Belgian side made full use of the defensive disorder in Peter Bosz’s team.

Writing in his column for De Telegraaf, the journalist highlighted how Club Brugge exploited PSV’s vulnerabilities to secure an important victory at the Philips Stadion on Wednesday evening.

Driessen even suggested that Club Brugge could claim the unofficial title of champions of the Low Countries after their win over PSV. He recalled that the equivalent distinction had gone to Royale Union Saint-Gilloise last season, when the Belgian side defeated the Dutch champions 3-1 in Eindhoven.

Although Driessen acknowledged that PSV had the better style of play, he felt the home side's attacking approach was undermined by missed opportunities and a lack of defensive organisation. Goalkeeper Yann Sommer also played an important role in keeping Club Brugge in the contest, making crucial saves as PSV searched for a second goal.

The decisive moment arrived in the 65th minute, when Carlos Forbs took advantage of the space left behind by PSV's attacking setup. Driessen pointed to Kostic's positioning as a significant factor, arguing that the Serbian was too far up the pitch when Club Brugge launched the counterattack.

Forbs, formerly of Ajax, had already wasted several counterattacking opportunities before making the most of his next chance. This time, PSV's disorganised defence had no answer to his pace and direct running.

Driessen praised the Portuguese forward's development since moving to Belgium, suggesting that he has become a more complete attacking player.

''In Amsterdam, it never came out because he keeps getting lost in the small space, but the forward has certainly grown in Belgium,'' Driessen wrote.

He acknowledged that some of Forbs' old weaknesses remain, describing him as quick but still prone to playing with his head down and struggling with his finishing. However, the journalist noted that the winger now shows greater awareness of his teammates, a development that has also helped him create more space for himself.

That improvement was particularly evident against PSV, where Forbs repeatedly threatened the home side on the counterattack.

Driessen reserved his strongest criticism for Kostic, who was unable to contain the winger once he found space to accelerate.

''And it must be said: his direct opponent, Filip Kostic, looked like a veteran once Forbs got up to speed and therefore was no match,'' he wrote, as quoted by PSV Inside.

The defeat exposed a familiar problem for Bosz's PSV: their attacking ambition can leave significant spaces for opponents to exploit when possession is lost. Club Brugge were prepared to take advantage, and Forbs eventually delivered the decisive blow.

For Kostic, meanwhile, the performance raised further questions about his ability to cope with quick, direct opponents. Driessen's assessment was clear: Club Brugge recognised the disorder in PSV's defensive structure and punished it when the opportunity came.
