Dambulla/Calcutta: Shikhar Dhawan has been in rich form of late. He was the Man of the Series in the Test series against Sri Lanka and now he has begun the one-dayers in a thumping fashion, hitting an unbeaten century on Sunday.

Dhawan's 132 not out helped India thrash the Lankans by nine wickets in Dambulla to go 1-0 up in the five-match series.

The opener, however, doesn't want to read too much into his good form and says that he stays prepared for a lean patch as well.

"I don't think about a slump (in form). When it has to come, it will come. I will embrace that period of slump as well. When I was not doing well, I was just focussing on my processes.

"And when I am doing well, I am still focussing on my processes. So those things don't bother me much. Failures teach you a lot. I'm lucky that I have learnt so much from failures," Dhawan, the Man of the Match on Sunday, said at the post-match media conference.

Speaking about his good form, the left-handed batsman said: "When I made a comeback in the ODI side in the 2013 Champions Trophy, I was batting like this. Even this time, in the Champions Trophy (2017), I was playing with a good flow.

"I would say that the way I am playing now is like I did in my debut Test (against Australia), or like I played in Galle in the first Test here. I am trying to keep repeating the same mantra for myself," he said.

While his captain, Virat Kohli, is already making his plans for the 2019 World Cup, Dhawan said that it was too early for him to talk about his chances being in the team for the mega event in England. But he added that he would try to keep performing in the lead-up to the World Cup and would also be alert about his fitness.

"It's a long time (until the next World Cup). I would like to keep performing well. That would be my goal because if I don't perform, there are such good batsmen in our side that anyone can take the place, so that's one thing.

"The second thing is I would like to keep my fitness on a high level because all the young boys are there. I like to keep myself fit, be with the pace of the game. Apart from these two things, I don't really have too many goals... Nothing like I have to score these many runs... I just focus on my process, including my fitness, skills and fielding," Dhawan said.

Dhawan appreciated the Dambulla pitch for being good for batting and also said that the current Sri Lanka team must be given time to perform better.

"I really didn't think about the pitch that much during the game. I was just watching the ball and playing the ball. But I felt that the pitch was very good, especially for the way Sri Lanka started the innings... I thought they will score 300 runs, but then they lost a lot of wickets in the middle, after which we dominated the game.

"This is a young Sri Lankan side and they are in transition period... The boys will get mature. In international cricket you need to have that experience. The young boys are good, with time they will get better," he said.
