The South African forward joined the Allsvenskan side on trial last month as he looked to impress the club's technical team.
Recent reports have indicated Ntuli has done enough to impress Djurgardens head coach Özcan Melkemichel and he could earn a loan deal.
However, the bulky marksman has stated that the Blue Strips are yet to make a decision on whether or not they are going to sign him.
“The first week was a little tough because I was not quite in shape when I arrived. But now I’ve improved and am back at my normal level‚” Ntuli told Djurgardens' official website.
“The level is good here and it shows that the competition is tough. Players work hard every day in training and the matches have good pace," he said.
“I’m getting to know the guys better and better‚ and I am trying to adapt to the kind of football that the team plays," Ntuli added.
“It gives me a new experience every day and a chance to learn more," the former Lamontville Golden Arrows marksman continued.
“We have not had any calls yet‚ but maybe we’ll sit down and talk later in the week. Then we’ll see what the situation is and what happens next," he concluded.
Ntuli spent the last three seasons out on loan at Platinum Stars from Sundowns, who recalled him at the end of the 2017/18 campaign.
The former AmaZulu FC frontman made 63 league appearances for Stars and he hit the back of the net 14 times during his three-year spell with the club.
