In an interview with ESPN, the Gunners star claimed he is not surprised by his current run of form as he claimed that his performance level has been the same as it was while playing for the Hammers.
Rice said, "I'll be honest, some people might stand here and say 'Yeah, I've surprised myself,' but I haven't. I was playing this well at West Ham, I feel like my levels at West Ham gave me so much confidence and belief in myself to have that belief I can be a top Premier League player.
"But the main thing was to be myself. Not to change anything. Just because I have been signed for £105 million, don't do anything different, just be myself. Things can unlock and so far things have gone really well. I've signed for six years and there is still such a long way to go in my Arsenal career."
