Jack Wilshere is enjoying his interchangeable role in Arsenal's 3-4-3 system and feels the London club have improved defensively after adopting the formation.
The 25-year-old midfielder slipped down the pecking order at Arsenal after managing only 17 games in two seasons blighted by injuries.
He made 27 league appearances for Bournemouth on loan last season before returning to Arsenal and played his first full 90 minutes for them in three years in the 1-0 League Cup win over Doncaster Rovers last month.
'I can play in the deeper midfield role, which I did against Doncaster, and then I went and played on the left,' Wilshere told Arsenal's website.
