De Jong has spoken about his fitness after linking up with the squad: "It's been a long time, playing for the Dutch national team. It's a great honour. I'm always happy to be here. I'm a bit sore, but I think it'll be fine. It was a lingering injury. I missed a lot of matches and the European Championship, which was difficult. Things are getting better now. I am growing back to where I need to be in terms of form and fitness. I think we have a good team, a good selection. Hopefully we can do great things."
