"This time it will be much closer than last time," says Arjuna awardee Grandmaster Abhijeet Gupta, who gave Carlsen the tag of 'favourite'.
Anand, who qualified for the rematch by surprisingly winning candidates' tournament earlier this year, backed his performance in the qualifier by winning the Bilbao Final Masters too and seems to be in fine nick ahead of the clash.
Carlsen was especially tentative in the Sinquefield Cup in United States a couple of months back where he finished a distant second to Fabiano Caruana of Italy.
While finishing second is never too bad a result, Carlsen's last tournament before the world championship must have dented his confidence as he finished three points behind Caruana.
"On the other hand, Anand has been at the top of his game with a few expected ups and downs. He won the Bilbao even though his last round loss might have been disappointing and he was clearly the best player in the Candidate's tournament where everyone made more mistakes than him.
