Clark is away on international duty at the moment, playing for the Republic of Ireland at the ongoing 2016 European Championship in France.
The centre-back, who can also play as a midfielder, has revealed a short conversation he had with new Villa manager Di Matteo.
"I didn't get a Face Time, I got a call from him,” Clark told The Birmingham Mail. "It was only a brief phone call just wishing me all the best for the tournament. Obviously we'll speak after the tournament has finished.”
Clark has been on the books of Villa his entire professional club football career so far and has a contract until June 2020, according to Transfermarkt.co.uk.
According to a report in The Sun last month, Premier League outfit West Bromwich Albion are interested in signing the Republic of Ireland international this summer.
The Villans got relegated from the Premier League at the end of the 2015-16 campaign and will feature in the Championship next season.
Clark is a good player, and Villa should try to keep him of him. Perhaps Di Matteo should sit down with the defender after the European Championship and convince him to remain at Vila Park for one more season at least.
