England will face Germany in Berlin but several of the Three Lions regulars such as Wes Brown, Rio Ferdinand, Ashley Cole, Joe Cole, Steven Gerard, Frank Lampard, Emile Heskey and Wayne Rooney has all pulled out.
Walcott told the Evening Standard: “The good thing about friendlies is you can tweak things and also try different things.
“I only played in the Trinidad and Tobago friendly in the summer and I didn’t expect to start in any qualifiers straight away.
“So it just shows if you’re training well, which I was, anyone can get a chance.”
