Newcastle United are a "really big team" that deserve success, so says Georginio Wijnaldum.

The Magpies have had a transformative 20 months since they were taken over by a consortium backed by Saudi Arabia's Public Investment Fund (PIF) in late 2021.

Under Eddie Howe's tutelage, Newcastle went from bottom of the Premier League at the start of 2022, to qualifying for the Champions League in under 18 months.

Wijnaldum spent a season with Newcastle in 2015-16 before he moved to Liverpool, and the Netherlands international hopes for the best for his old club.

"Really happy because Newcastle's a really big team," the midfielder told reporters after the Netherlands' Nations League loss to Croatia.

"I think a lot of people underestimate how big the club is and how loyal their supporters are.

"When I was there, I saw how hard they were trying to get results and to finish as high as possible and also the fans, who were standing by the team were amazing.

"So I think they deserve it. How they managed it throughout the years. I think they deserve how it is going right now."

Switching focus to his own future, Wijnaldum – who spent the season on loan at Roma from Paris Saint-Germain, but suffered a tibia fracture at the start of the campaign – conceded he is unsure over his next move.

"I don't know [what will happen]. I think it will be a surprise for everyone and also for me," he said.

"I just see what's going to happen and what options I will get and then you're going to see what's going to happen."
