"If the gaffer wants me to come off the bench and change games I will do that," said Blake, who has joined on a one-year deal with an option for an extra 12 months. "I see that as a compliment not a negative.
"Everybody has got to fight for a place and I don't expect to walk straight into the team. I want to fight and earn my place and, if I can do that, I can stay in the team."
And Blake is delighted to be reunited with Coyle once again. He said: "He's the best manager I've ever had and brought the best out of me.
"It's fantastic to be given the opportunity and, hopefully, I won't let him down and will do a good job.
"We've got a good set of players here. There's a lot of quality and, with the gaffer we've got, I'm sure we can climb up the league."
