Swedish football expert Jonas Hansson told BBC Radio Newcastle that new Sunderland signing Melker Ellborg "has all the qualities" you want from a goalkeeper.
The 22-year-old joined from Malmo for £3m in the winter transfer window and has signed a deal that will keep him at the Stadium of Light until 2030.
"They are getting a goalkeeper that basically has all the qualities that you want," Hansson said. "He's quite big, he's quite strong, he's got game-winning saves on his resume, quite a good passer with the feet.
"He has brought stability to Malmo and a great personality. Everyone I talk to says how wonderful he is, how sweet and nice and super-professional and hard-working, so you're basically getting a really, really strong package."
The Swedish shotstopper has experience at the highest level with appearances in both the Champions League and Europa League.
Speaking after signing for the Black Cats, who are just five points off the top four in the Premier League, Ellborg said: "I always like to work hard in training and never stop. I want to keep developing all the time, especially when things are tough and things are going against you. I always want to keep working.
"That is what is so great about this club and that is the feeling I have got from my conversations with the players and coaches so far.
"It is a club built on a working mentality, which I really like and agree with – this suits me well."
