The new contract was signed by Thomas Frank.
The new deal with the Bees was only signed in January and was to last until the end of the 25th season.
The club was in the top flight for 18 months before finishing 13th.
On December 26th, they will face Spurs.
The warmth, support and kindness every time I meet a Bees fan has been amazing and it gives me extra energy to continue the work.
In the first season we attacked the league, and in the second season we are attacking it.
I hope to continue our progress and create more magic moments.
Frank was an assistant to Dean Smith when he took over as Villa's boss.
