The Mercedes pair have dominated the opening rounds of the 2019 world championship, taking all of the available race wins in an unprecedented five straight one-two finishes to start the season.
Although Hamilton leads the championship battle after the Spanish Grand Prix, Wurz believes Bottas can fight for a world title this season.
“He can and should fight for the world championship,” Wurz told Speedweek.
“Last year he had some technical bad luck and was not yet so well established in the team. But he has set himself up well in the winter and now drives with confidence.”
However, Wurz also added he expects the gamesmanship between the two to ramp up soon, hinting at Hamilton's time with Nico Rosberg as Mercedes teammate.
“You can already notice the first little taunts. The better Bottas does, the more Hamilton will react.
“It will be fascinating to see what happens.”
