The 26-year-old almost joined Hull City on the final day of the August transfer window but has received assurances from Baggies boss Steve Clarke that he is wanted at the Hawthorns.
Long, who scored his first goal of the season in last weekend's 2-2 draw at Chelsea, has been linked with a move away in January but is thinking of nothing other than cementing his place in the team.
The Republic of Ireland striker said: "I have always been wanted there. The gaffer said he wants me, I am a big part of his plans and I enjoy playing for him as well.
"I am just concentrating on my football at West Brom and if a new contract doesn't get sorted out, then I'll have to look at pastures new.
"But at the moment, I am letting that take care of itself."
Long has started only five league games for the Baggies so far this season, with injury interrupting his progress.
However, he is currently the man in possession of a striking berth and knows he needs to increase his goal tally if he is to remain there.
He said: "I picked up an injury after the second or third game of the season and missed out for two or three games, and then the lads were flying, so it was hard to get back into the side.
"But I got the nod against Crystal Palace and then again against Chelsea, and I feel like I am playing well and hopefully I can keep my place in there.
"You can do so well on the pitch but it's goals which keep you on there, so I am trying to tighten up on that and hopefully I can keep scoring between now and the end of the season."
Long did just that on Friday night, when he came off the bench to cement a 3-0 friendly victory for Ireland over Latvia with a 79th-minute strike.
