Having played alongside Isak for the Swedish national team, Elanga is familiar with the forward’s movement, mentality and qualities on the pitch. Their existing chemistry could be an asset for Newcastle heading into the new season, especially if the club can hold onto their prized striker.
He said: "Alex is one of the best players in the world - there is always going to be noise around him. He's somebody I know from my national team, so I know how good he is."
Speaking about his decision to leave Nottingham Forest and join the Magpies, Elanga revealed teaming up with Isak again was among several motivations.
"There were a lot of factors that played into it," he added. "The city, the fanbase, as well as Alex, Anthony Gordon, Bruno, Joelinton, Joe Willock and also winning a trophy after 70 years. Getting that winning factor back into the city. They came so close but now they have a trophy. I think that played a huge part. You can see in training, the intensity and competitiveness, it is second to none."
