Yes the Dutch league is a lesser league.
One the thing to remember is that Dutch League ended last May, whereas our guys have played 20 games since then. So Im sure of his match fitness or form when he joined. Whilst Donny is a technically superior player, he has massive adjustments to make with new inter team relationships and style of play, much higher intensity league re-aquiring form, fitness and momentum. Lets not forget how log in took Fred to make these adjustments.
He also entered during a shitstorm of unacceptable defeats so we suddenly found ourselves in mini crisis of MUST WIN games, where squad rotation went out of the window. And all these are high energy pressing games in which Ole believes he needs his Mc-Fred double pivot, instead of a single destroyer with two baller players in front of him.
Let's get through til next international break, when we will play a lot more 'weaker teams' who will use a low block, and that's when I can see Donny getting his proper introduction into starting successive games, and he can start to make his case.
