MotoGP championship leader Valentino Rossi has claimed that Marc Marquez will become a "problem" again as the season continues.
Rossi extended his lead over Jorge Lorenzo in the standings by 10 points by winning the Dutch MotoGP at the weekend.
Marquez is currently fourth in the rankings, but the Spaniard showed his intent by duelling with Rossi until the end of the race in Holland.
"First of all, I'm very happy for my [points] advantage over Marquez," he told Motosport.com. "For me, from now until the end of the season he will become a big problem again."
Rossi has a 74-point lead over Marquez, who is the reigning champion.
