Three Lion starlets receive manager's support...
The young trio were called up to the senior squad by Fabio Capello on Saturday after they all featured in the Gunners thrilling 6-5 victory over Legia Warsaw.
It will be the first time Walcott has featured for the Three Lions since his surprising ommision from Capello's World Cup 2010 squad earlier this summer.
Wilshere and Gibbs have never represented their country before, despite impressing last season. However, Wenger believes all three will shine as Capello aims to rejuventate the squad following a lacklustre showing in South Africa.
"Kieran Gibbs is slowly coming back to his best. That is good news for us and for England I believe," Wenger told Arsenal's official website.
"[Theo] Walcott and [Jack] Wilshere were a little jaded today [Sunday] but overall they have had a very sharp pre-season campaign."Gibbs, 20, has 14 England Under-21 caps and has played 30 times in all competitions for Arsenal since breaking into the first-team in 2006.
Wilshere, who has been widely backed to be one of England's future stars, spent the majority of last season on-loan at Bolton Wanderers. The 18-year-old midfielder made 14 Premier League appearances last campaign, scoring once.
