The 19-year-old Chukwuemeka will be joining the Blues for a fee of 20 million dollars.
The teenager was left out of Villa's pre-season tour to Australia because he wouldn't sign a new contract.
After starring for England in the European Championship, Chukwuemeka made 12 appearances for Villa.
The third signing of the summer would be him.
La Liga giants Barcelona, Serie A champions AC Milan and Bundesliga side Borussia Dortmund were all linked with Chukwuemeka.
The deal can be seen as a coup as he is one of the best young players in the league.
Chukwuemeka has been granted permission to travel to London to have a medical and discuss personal terms.
Villa boss Steven Gerrard said last month the player had not signed a new deal which "has been in place for some time now" after leaving him out of the tour down under.
In the last year, they've brought in England international Raheem Sterling from Manchester City for £50m and Kalidou Koulibaly from Napoli for over thirty million dollars.
The boss wants to strengthen the side. After discussions with Manchester City over the sale of the Spanish left-back, he is interested in signing another one.
