Friday's two sailings in the Portuguese Vilamoura were carried out in changing winds around 4-6 m / s and the Swedes sailed stably without impressing - but also without taking any chances.
In the first race they finished sixth and in the second it was a tenth place.
But they increased their lead in the total.
“We wanted to sail as well as possible but with slightly less risk.
So we are very happy with the first race.
In the second race we did not really get going at the start and missed the first shift which made us slip in the back of the fleet.
But we kept an eye on the Portuguese and managed to get a few boats in between that give us a better starting position for tomorrow ", says Bergström in a press release.
Good starting position for the gold
Home jumpers Diogo and Pedro Costa can still sniff the Swedes for the gold.
But then the Portuguese must be at least six places better than the Swedes in the final sailing on Saturday, where the top ten will settle for the medals.
The Spaniards Jordi Xammar / Nicolas Rodriguez, who is third, also have a very small opportunity to pass the Swedes in the total.
But then the Spaniards must win on Saturday at the same time as Anton and Fredrik will be last.
"It will be a really exciting medal race tomorrow.
The conditions for the race in terms of points are to our advantage.
But in the medal race there are double points and it is expected that offshore winds so much can happen.
But of course we go for the gold ", says Bergström.
The Swedes have no World Cup gold since before, but silver from 2017 and bronze from 2019.
