No matter how close the grain is on the piece you have to replace the torn out spot you cannot conceal the patch because it's broken across the grain. It will always show and will always be an eyesore UNLESS you do an opaque sunburst to cover it.
Unless you want to consider this project a practice piece I'd replace the top and first look into why that happened. If you want to keep what you have and fix it there are good guitar building and repair videos on youtube. To explain all this here would require too many words/
