The Hammers go to Dean Court on the back of two consecutive home wins.
Nuno said, "I think it was a needed break.
"Our international players have returned over the last couple of days. Some of them are happy, and some of them are not so happy! Overall, I think the break was needed.
"The hard work continues, and the good results we achieved are in the past now. We’re still working to improve, and to be able to sustain our performance for longer periods, and that’s what we’ll be hoping to do on Saturday."
On the Cherries, he said: "We are talking about a very good team, who have a fantastic manager in Andoni (Iraola). I’ve known him for some time now, and I really admire him.
"For sure, they are going to be a tough opponent, and past form goes out of the window. Whether it’s good or bad, it’s over now, and Saturday is going to be a new game for both teams."
