Villas-Boas recently admitted he made a mistake by letting Dawson speak to QPR, and the player himself is grateful to the Portuguese for giving him a second chance at Spurs.
"The gaffer has been very honest with me from day one," the former Nottingham Forest man said.
"I spoke to him after pre-season and he told me there might not be as many opportunities as I would have liked. It was my decision to stay and fight for my position.
"I was out there every day training hard and thankfully the manager has seen that and he has put me back in.
"As a player you can only ask for honesty. The manager has been great. I'm glad to be back playing."
