As a Belgian I'm proud for Openda getting a big move like this. Good for him. But I genuinely do not see him as a starting forward for a club our size. He's a decent player, tremendous workrate, does what the coach asks him to do. But surely he does not have the skill you'd expect from most players on our level and I'm not sure how much he will be able to improve.
Best of luck to him though, hope he does well.
