You can say what you want, obviously.
All I would say, as someone who works as part of a close-knit team, is that we win as a team and we lose as team. Apportioning blame is always easy but rarely beneficial.
Finger-pointing achieves nothing.
No player should be immune from criticism, but Knockhaert has won us WAY more points than he has cost us this season.
Without his goals and all-round performances we'd still be trying to secure a play-off place at best.
