Despite claims in the media following his debut against Reading, he is quite relaxed about a permanent move even though his contract at Everton does run out this summer.
For the moment, he - like Trevor - is just looking at the next month, and he says:
"It is good under Trevor, even though he is just short term, and hopefully it will be an enjoyable month."
Whether Niclas then stays longer, as he has the option to do if he is required, remains to be seen, and he says:
"That might be the story of it but I will just concentrate on my side of things and I am sure it is being sorted out the right way.
"I am aiming to start games which I did on Tuesday so it is just taking it from there."
As for his first game at Upton Park, he says:
"It was a competitive game and it is always hard to come from the bench and straight into it but saying that I enjoyed every minute of it and it was nice to get off to a winning start."
Indeed, he nearly scored with his first touch in a claret and blue shirt - a magnificent header - and he recalls:
"It would have been a great goal but the keeper made a great save; I am not usually scoring from headers so that would have been a great story but the main thing is that we held on and got the points."
"We could have scored three goals in the first 10 minutes and maybe killed the game but in the last 20 minutes of the first half they came at us a little bit and it started the same way in the second half.
"Then we went to 4-4-2 and it felt like there were chances at both ends."
He says he is delighted with the welcome he has had at the club, adding:
"That always helps; everyone at the club has been really great to me and when you feel the support from the crowd as well it makes it easier.
"So hopefully we will keep winning games as we did at Crewe."
