The 21-year-old joined the Bundesliga side in the summer of 2011 from 1860 Munchen and has since impressed at the biggest stage.
After netting 6 league goals in his first season at the club, Volland has already registered 7 goals this term, and has in turn impressed the visiting scouts.
As a result, Bayern Munich, Arsenal, Manchester United, Chelsea and Liverpool are all believed to be keen, although they have yet to make their interest concrete.
Volland has a contract until June 2017 and is valued at £12 million, with the asking price unlikely to put off any of his suitors.
Hoffenheim did well to hold mighty Borussia Dortmund to a 2-2 draw at the weekend, with Volland scoring the second goal for the side that currently sit in 11th place in the Bundesliga standings.
