“I feel good, I have had a full pre-season behind me and I have come back in really good shape," said Tarkowski to Lancashire Evening Telegraph.
“That has allowed me to get to the level of performance that I want. I have still got to prove myself at this level and that is what I am looking to do.
“I am always looking to improve and I still feel like I am at an age where I have progress to make and I will be looking to do that as well.
“I am always looking to be see if I I am going to be involved, I always feel as though I am working hard enough especially recently, I feel like I have been performing well.
“I have not made it, which is obviously disappointing, but that shows I still have to work to do and I will be working as hard as ever to show that.
“I am sure the England manager will be watching me amongst many other players, I have just got to keep performing and show what I can do."
