Damian Lillard believes changes need to be made by the Portland Trail Blazers if they are to end their now 44-year wait for an NBA title amid swirling speculation about his future.

A report on Friday suggested star point guard Lillard will request a trade from the Blazers having spent his entire NBA career in Portland.

He will reportedly address those claims during a media availability session for the United States' Olympic basketball team on Friday.

Lillard has been named an All-Star six times in his career and has helped the Blazers reach the playoffs in each of the past eight seasons.

It is his clutch shooting that has consistently kept Portland in the mix and, since he entered the league in 2012, only Stephen Curry (2,460) and James Harden (2,125) have made more three-pointers than Lillard's 2,051.

Portland reached the Western Conference Finals in 2019 but were swept by Curry and the Golden State Warriors.

However, this season's exit at the hands of the Denver Nuggets in six games was their fourth first-round elimination in five seasons and led to the Blazers parting ways with head coach Terry Stotts. Chauncey Billups is the man now tasked with leading them to a first NBA Finals since 1992 and a first championship since 1977.

Asked by Yahoo Sports if the Blazers have matched his commitment to the franchise, Lillard said: "To make it to the NBA, I had to give it everything I had.

"I was going to do what needed to be done to win games. I didn't come into the league worrying about what others were doing in the organisation. I didn't come in with that type of mentality.

"But I've been active in probably 95 per cent of the games in my career. I've played through injuries, and I've been a part of two rebuilds. I feel like I've experienced everything with the Trail Blazers, and I've worn that jersey as a badge of honour and with a lot of pride and care.

"I never felt like my job was to go in and critique what other people were doing in the organisation. My job was to make sure the team is functioning and trying to lead them to the best results. I've always assumed everybody’s mentality was the same.

"Even when I'm playing well and we come up short at the end of the season, I go home and the first thing I do is look in the mirror and tell myself we didn't win a championship. Or if I didn't play as well as I should have, I've had to look in the mirror and tell myself that my performance was unacceptable and I have to do better. And then you go do better.

"I think that's the stage we're at as a team where we all, not just me, not just my team-mates, not just our new coaching staff, the front office, everybody in this organisation must look in the mirror because we've constantly come up short.

"We have to look in the mirror and say I have to be better because whatever it is we're doing is not working and it's not giving us the shot to compete on the level that we want to compete on."

On why he feels this is a pivotal juncture in his career, Lillard added: "There are a few reasons: One being I'm not getting any younger. Our environment has always been great.

"We're not losing a lot, but we were eliminated by a shorthanded Denver team that I felt we should have beat. I just walked away from that really disappointed. I was like, 'Man, this just isn't going to work'.

"We're not winning the championship, but we've got a successful organisation. We're not a franchise that’s just out here losing every year and getting divided.

"We have positive seasons; we just don't end up with a championship. So I feel like at this point, I basically made the decision that if you do what you've always done, you'll always be where you've always been.

"Just like I hold myself accountable for a bad performance or hold myself accountable to make sure that I work my a** off when I’m training, I must be accountable for saying what needs to be said even if it's not popular. And that just comes with age.

"When I was younger, I felt like maybe I'll be out of place, but I feel like I've earned the right to say we must do better. We must do better if we want to win on that level."
