The defender was on the scoresheet in the loss to Watford.
The Villans are set to play in the Championship next year after a disastrous campaign has seen them drop out of the Premier League.
A huge summer overhaul of the playing squad is expected, with the club likely to be keen to get rid of those that have disappointed and reduce the wage bill in one go.
There are calls for the side to introduce their homegrown players into the squad as a result, and Keown says Clark is one of the players to build around next year.
"The away fans at Aston Villa are sensational,” he told BBC Sport.
"Clark is one of the players to build around next season. He gets his head on it, first class. There is one for the future."
There are certainly worse players that Aston Villa could look towards to form the spine of their team next season.
Of all the squad this season, nobody has performed well, but it is fair to suggest that Clark has not performed badly either.
At just 26-year-old also arguably has the best years ahead of him and if the club can find a reliable central defensive partner to go alongside him, then he could easily be one of their key men next year.
