Finn, 21, doesn\'t consider himself certain to play in the first Gabba Test.
Adelaide: Steve Finn may be dubbed England's great bowling hope for the coming Ashes series but he said on Wednesday he just wants to make himself an indispensable member of the team.
The Middlesex giant, who has modelled his bowling action on Australian great Glenn McGrath, is determined to become "undroppable" in the five Ashes Test series, which gets underway in Brisbane on November 25.
Finn, 21, doesn't consider himself certain to play in the first Gabba Test despite the impact he has made in his eight Test appearances.
"I'm just trying to make myself undroppable," Finn said ahead of England's second tour match against South Australia, starting in Adelaide on Thursday.
Finn, who was crowned with the International Cricket Council's emerging player award this year, is an unashamed fan of the Australian fast bowling great McGrath.
"I have watched lots of videos of him bowling and I watched him bowl a lot when I was younger," Finn told reporters.
"He's probably the best seam bowler to ever play international cricket in my eyes.
"Just to watch him bowl -- he's great, he's fantastic."
Finn is considered to have a similar textbook action to McGrath, which produces unerring accuracy and steepling bounce.
Finn played down suggestions he could prove the difference in his first Ashes series after taking 32 Test wickets at 23.22.
"To play in an Ashes Test match and an Ashes series would be fantastic, it's something that I have been thinking of since I was younger," Finn said.
"I'd relish it if given the opportunity but there are two more warm-up games to come and I'm not looking towards that first Test yet."
