According to the British media "Mirror" quoted by Spanish media Corbe Radio, Villa coach Gerrard personally called to invite Coutinho to join.
Radio Corbe said Villa sold Glalish to Manchester City for €100 million in the summer window, which gave them plenty of transfer funds in the winter window and they hoped to strengthen the squad in January.
After Gerrard took over as Villa manager, the team's performance has improved significantly, but it is still not able to meet Gerrard's requirements in midfield, so they hope to sign Coutinho, and Gerrard even personally called to invite his former teammate to join.
Barca also hope to get Coutinho out as soon as possible to register new signing Ferran Torres.
