Ekitike opted for Liverpool over Newcastle and joined the Reds from Eintracht Frankfurt in a deal worth around 80 million pounds.
The 23-year-old has had a dream start at Liverpool, grabbing three goals and an assist in his first four competitive appearances for Arne Slot's side.
Despite this, Ekitike may soon be out of the team as he faces a fight with Isak over minutes following the world-class striker's 125 million pounds move to Anfield on deadline day.
The arrival of Isak means Liverpool are spoiled for choice in attacking areas, with Ekitike insisting that he wants to ensure that Slot has a "problem".
"It's fun. When you play for the best teams, you expect to be competing with the best players," Ekitike said when asked about Isak's move to Anfield.
"Isak is a player I've watched too, so seeing him arrive is a pleasure.
"It's going to be tough competition, but I'm going to focus on performing well so that it's a problem for the manager."
He added: "Obviously my life has changed.
"It's a big move and I'm watched a thousand times more, but I'm taking it positively, it's really good. It's the position I wanted to be in.
"When you have this kind of standard, you have to show that you belong here and you have to continue to perform.
"But it's a position that I like and that I want to keep."
