Addicks boss Chris Powell snapped up the youngster from non-league football in the summer of 2011 and he has gone on to become a first-team regular with the Championship side, having helped them secure the League One title last term.
Following some impressive performances in the second tier this term, it appears a number of top-flight managers, including Villa's Paul Lambert and Fulham boss Martin Jol, are set to offer him the opportunity to cut his teeth in the Premier League.
If any club does step up their interest in Pritchard they will face a battle with Powell to take him as he recently warned rival clubs off making bids for his key men in the transfer window. But he stressed that every player has their price and will be sold if the valuation is met.
Powell said last month: "It is a part of the job I don't really like because they upset a player who is quite happy here and you want clubs to do it the right way.
"Hopefully if clubs do come in for any of my players if they do it the right way then we will stick to what we believe is right. If both parties agree then the player goes."
