Allen admits his recent performances haven't been good enough.
Asked about the criticism from Shearer and fellow pundit Mark Lawrenson, Allen said: "When Alan Shearer speaks, people listen - his career and experience is incredible.
"I'm looking to use it as a springboard to help improve my game. It's always interesting to see what those players have to say.
"I want to improve all aspects of my game. I'm a perfectionist and maybe that's part of my problem.
"Sometimes I get frustrated and disappointed when things aren't perfect. In terms of what Alan said, I can try and learn from it.
"It's difficult because at the time I thought I was playing well!"
