Cleveland Cavaliers star LeBron James has insisted that his relationship with Dan Gilbert is much improved following his return to the franchise this summer.

The pair fell out publicly four years ago after James left the Cavaliers to join the Miami Heat, where he won two championships in four years.

"I think it's really good," James told reporters.

"We had one bad moment, and it just overshadowed all the great times we had together, and now we're back together."

James insisted that the pair share a common goal which is to bring a championship to Cleveland, but Gilbert refused to provide any predictions on how he believes the team will fare this season.
