England are currently playing good cricket but India has the wherewithal to beat them in their own den in the upcoming tour, reckons India's middle-order batsman Yuvraj Singh.

India will play a four-match Test series, five ODIs and a one-off Twenty20 match during the tour, starting July 21.

"England is one of the best teams but we've been maintaining the number-one ranking for two years and we won in England last time, and I'm sure if we play to our best potential we can win again. England are playing really good cricket," Yuvraj said.

Yuvraj, who returned to the Test fold after a long gap, said he himself is keen to do well in the five-day version of the game.

"In terms of one-day cricket everything has been good for me but in terms of Test cricket I suppose the graph reads a bit up and down. Cricket is my game though and I am going to give this Test series my level best, I will give my 100 per cent," he told ICC's Cricket World Radio Show.

Looking back at the tough times he went through ahead of this year's ODI World Cup, where he emerged as player-of-the-tournament, the left-hander said that phase only made him stronger.

"There were times when things were harsh but these kind of experiences made me stronger as a person. I don't think if I'd not gone through that phase I would have done so well at the World Cup -- I think it helped me to understand how important the Indian colours are for me and I now understand how to get better from here," Yuvraj said.
