The Scots' hopes of reaching Brazil next year are all but over after taking just two points from their first four Group A games, and a hammer blow to their chances came last October when the Tottenham player scored two late goals to seal a Welsh win in Cardiff.
After Gordon Strachan got his tenure as Scotland manager off to a winning start thanks to a Charlie Mulgrew goal against Estonia, attention turned to the double-header at home to Wales and away to Serbia, with Berra pinpointing the obvious danger in the first game. The Wolves defender, 28, said: "We definitely want to get three points against Wales."
He continued: "We should have got them away from home and would have if it wasn't for Bale sticking in a world-class goal and scoring a penalty. At 1-0 up we were comfortable, they weren't threatening us and then they got a penalty out of nothing.
"It could still have been 1-1, they weren't putting us under severe pressure but the next thing Bale sticks the ball away from 35 yards. What can you do about it? This is why he is rated at £40million or so, (and why) Real Madrid supposedly wanted to sign him after that. We know he is a world-class player and we have to limit him to very few chances.
"I played against him at club level and sometimes, when these players are on their day, there is nothing you can do but hopefully he has an off-day. He is one of these players who have everything, he is an athlete and he has a great touch. He can do nothing in a game and the next thing he puts one in the top corner.
"Against West Brom the other day, a couple of players tried to tackle him and he wasn't happy but the ball came to him and boom, he smashed it into the net. Sometimes you just have to put your hands up and say 'well done'. But as long as we are disciplined and compact, and attack and defend as a team, then we have a chance."
The former Hearts defender insists the transition from Craig Levein, who departed last November, to Strachan was seamless and was encouraged by a solid performance against Estonia.
"The majority of the squad is still here, apart from maybe Chris Burke who came in, so it has been business as usual," he said.
"Unless you play for clubs like Manchester United where the manager is there forever, you get used to it. Managers come and go like players come and go. It is a fresh start and it gives everyone a little more energy to go and impress."
