The Ghanaian international says he is happy to be working with the Spanish coach.
The 25-year-old moved on-loan to the Tyneside club from Chelsea during the summer, and has played a key role in the side’s fortunes so far.
The Magpies secured qualification back to the English topflight after defeating Preston North End 4-1 on Monday.
Key to their qualification has been manager Raphael Benitez, who decided to stick with the club after they were relegated from the Premier League last season.
And Atsu has now praised the Spanish coach, insisting his supportive nature helped bring out the best in all the players.
“Benitez is a great human being and he was very supportive of the players," Atsu said in an interview with the BBC.
"I was really happy because he got all the players involved in matches.
"That is difficult for most managers to do.
"However, he made sure each and every player had a part to play and everyone is really happy at that.”
Atsu has scored four goals and registered a further four assists in 13 games so far this season for Newcastle United. However, it remains to be seen if the club will make his loan move permanent.
