Alexander Isak must step up and become a leader for Newcastle United, just as he is with Sweden, following his £58m summer move.
The 22-year-old has arrived for international duty with his country for the first time since becoming a Magpies player last month. Isak will be involved for the upcoming friendlies with Serbia and Slovenia and is expected to be handed a great deal of responsibility in the national setup.
Despite his age, Isak has been a regular for Sweden for over five years and is already one of the leaders in Janne Andersson's squad. The national team boss this week reminded key players, including Isak, of their responsibility on the international stage.
