Carmelo Anthony Guarantees NBA Return This Year, Then Signs With Portland!

Carmelo Anthony tells TMZ Sports he WILL be back in the NBA this season -- and he's even open to returning to the New York Knicks!

Everyone's been wondering about Melo's basketball future ever since he parted ways with the Houston Rockets back in January.

35-year-old Anthony has previously said he wants to get back in the league -- however, no one has pulled the trigger yet.

But, it sounds like Melo's got something cookin' ... because when we saw the 35-year-old leaving The Henry in L.A. on Wednesday night, he was VERY optimistic about his return.

"We're figuring it out," Melo told us ... noting that he was NOT in town to speak with the Lakers or the Clippers.

When we pushed back and asked if he'll be on a roster this season, Melo told us ... "For sure. 2000%."

There are reports the Knicks could be interested in Anthony -- interesting considering the way things ended back in 2017 -- but Melo says he's down to return.

"We open man. We open to every opportunity."

In fact, Melo even defended Knicks head coach David Fizdale ... saying the team's lowly 2-9 record isn't all his fault ... "It's a lot of things that goes into that."

So, where will Melo end up this season? Stay tuned ...
