New York Knicks star Carmelo Anthony has revealed his frustration with calls from the officials during the loss to the Houston Rockets on Thursday night.

While the Knicks forward had 11 free throw attempts during the 109-106 defeat, rival James Harden was able to get to the line with 18 attempts of his own.

"You look at that and you see the way that some guys get their calls; me, I got to get cut, you've got to see blood for me to get a call down there," Anthony said, according to ESPN.

"That's where the frustration comes from."

The Rockets guard led the NBA in that category last season, and is currently third this year after he went 16-of-18 from the line on Thursday.
