Alan Pardew's side were the subject of speculation about behind-the-scenes splits between the English and non-English speaking members of their squad last season as they struggled to a 16th-place finish in the Premier League.
But as the new campaign draws closer, Anita expects the squad to be more united now that more of them speak English, and is predicting a better showing at St James' Park as a result.
"The communication is much better now, everybody can speak English now as well, so it is easier for everybody to communicate with each other and with the supporters," he told reporter's after Newcastle's 4-2 win over Motherwell.
"We have had six months now to know each other as a group, we know each other better. We have no excuse this season to do badly. It has to be good."
Anita was one of several new faces to join Newcastle in August 2012 and the former Ajax man cannot wait to get started with his first full pre-season at the club."This is my second season, I know what to expect now," he added. "The whole team now knows what to expect because the whole team did not know too much about how different the Premier League is to other leagues.
"This year we must improve and I think we will do well. It will be nice that all of this squad have a full season together. The coach wants us all from the start so we are all settled and together.
"I knew that it was going to be very, very tough, totally different to Holland. It is all about improvement. We have to keep together and work hard on and off the pitch.
"The guys who came in in January also are here for the new season, so there is a good feeling building between everyone. Hopefully we will see that on the bench."
