Former Holland star Rafael van der Vaart has rapped Manchester United boss Erik ten Hag for persisting with Scott McTominay in midfield.

Casemiro was once again a substitute as Manchester United succumbed to a heavy defeat at the hands of their rivals Manchester City in the derby on Sunday.

Joining an ever-growing cast of former players to have criticised Ten Hag's team selection, Van Der Vaart said his compatriot had created a rod for his own back in not throwing Casemiro in from the start.

"Ten Hag should have started playing Casemiro straight away," Van Der Vaart said on Ziggo Sport.

"McTominay starts performing and Man United start winning and then of course he can't put McTominay out of the team anymore. I find this very stupid from him because you are creating your own problem."
