Jack Wilshere says feeling he should be in the England squad does not mean he is "self indulgent" as he hit out at a journalist over his World Cup snub.
Wilshere was among the headline absentees from Gareth Southgate's 23-man squad for the tournament, along with Manchester City goalkeeper Joe Hart.
The Arsenal midfielder did not make Southgate's reserve list either, with the manager indicating his drop in form toward the end of the season had played a role in his omission.
Wilshere - who made 38 appearances this season - subsequently complained about his exclusion, writing on Twitter: "I should be in the squad!"
The 26-year-old Wilshere argued after a strong season by his standards he had the qualities needed to make "a real impact." However, he also noted in his two tweets that he respected the manager's decision and will be rooting for the Three Lions in Russia.
Wilshere's outspoken response drew a mixed response and he responded angrily to a journalist who criticised him and suggested he had been badly advised on Friday.
"And what would you know about me or who gives me advice?" Wilshere posted on Twitter.
"Because I believe I should be in the squad means I'm being self indulgent? You know nothing."
England start their World Cup campaign against Tunisia before taking on Panama and Belgium in Group G.
Meanwhile, Wilshere's contract with the Gunners expires at the end of June, meaning he could have a new home next season.
