AVB actually wanted to sign Parker last season while at Chelsea.
He told the Sunday Telegraph: "Even our fans were a little bit 'is he the right man?'. But he's turned everyone around. He's done fantastically well. Since he's been here he's been a credit to himself, he's building a team, built a very good team spirit.
"He's very open, his man-management is very good, he speaks to the players very well, he's very well organised. As a player the one thing you want above all from a manager is that he's straight with you and he's very honest."
