The 26-year-old centre-back is happy to be in the squad with the other lads.
But he has no qualms about admitting that he wants to grab his chance if he starts, given John Stones is injured for these upcoming qualifiers against Czech Republic and Montenegro.
"Obviously Stonesy isn't here so there is a position vacant at the moment," said Tarkowski to reporters.
"I want to be a part of the team and be playing, but I understand how hard it is just to make the squad never mind make the starting XI. But I will be doing everything I can to impress.
"It is nice to know that the people in charge of picking the teams believe in the player you are and what you are doing.
"I don't think I am the finished article. I always work hard on my game to improve and, knowing the managers are backing the work I'm doing, it gives you the confidence to go out there and show what you can do."
