It has been reported by the British newspaper that Villa’s Premier League rivals, Liverpool and Newcastle United, are also chasing the 21-year-old midfielder.
Cousins is one of the more promising young players in the Championship and was in good form for Charlton in the recently concluded 2014-15 campaign.
The midfielder scored three goals and created 34 chances in 44 league appearances for Guy Luzon’s side.
The England Under-21 international had a pass accuracy of 73% and a shot accuracy of 26%, and won 88 headers, 24 dribbles and 57 tackles.
Cousins can play in central midfield, on the left of midfield and in defence. Charlton finished 12th in the Championship in 2014-15 with 60 points from 46 matches.
It would be a blow for the Addicks if the youngster were to leave this summer. But if they get a good transfer fee, then they should be able to sign a suitable replacement.
