Juan Sorin, a player once linked with United:
"Gabriel is very important to the defence and to the team. He's a strong player, technically solid and with a lot of experience in the national team.
"But he has improved during his time at Manchester United and that is good for us. He is learning about how to play these big games and he is helping the other players.
"Playing for such a big team has helped him and that is good for Argentina."
