Wolves crashed to a 3-0 defeat at Blackburn on Saturday to remain a place off the foot of the Barclays Premier League ahead of crunch clashes at home to Birmingham on Sunday and at West Brom seven days later.
Despite the club's plight, Berra said: "We will keep on fighting as we did on Saturday when we kept going and the fans could see that.
"We've been here many times before in terms of having to bounce back and that's what we'll do.
Speaking to the club's official website, the 25-year-old Scotland international added: "There are two big derby games coming up and we know City and West Brom are two good teams with good players.
"Birmingham is the first one and we're back at home and will definitely be up for it."
