Jack Wilshere has admitted his shock after Fabio Capello resigned as England manager on Wednesday night.
Capello stepped down following a meeting with Football Association chiefs at Wembley Stadium.
Arsenal midfielder Wilshere won his first cap under Capello against Hungary in August 2010.
The 20-year-old said on Twitter: "Shocked about news on Fabio Capello...gutted to be honest, gave me my 1st cap and believed in me! Thank you Mr Capello! #GreatManager.
"People have there (sic) own judgement on Capello but for a young player who was given the chance to play for my country at such a young age...
"He has shown great belief and trust in me so I can only thank him....massive influence on my career so far! Sad to see him go!"
Like Wilshere, Tottenham defender Kyle Walker took to Twitter to express his disappointment at Capello's departure.
He posted: "Gutted to see Fabio Capello go he put a lot of trust in me and gave me my first cap just want to say a big thanks really.."
Former England captain Gary Lineker backed Walker's club boss for the top job, claiming he could manage both England and Spurs in the short term.
He tweeted: "As you ask I think new man should be English. Players have to be, so should boss. HR the man if he wants it. He can do both jobs til May."
QPR midfielder Joey Barton was typically forthright in his assessment of where Wednesday night's developments, which followed John Terry being stripped of the captaincy, left the England team.
"Well, well, well, this debacle claims yet another victim. Where does this stop. £madness," he said on Twitter.
"No captain and no manager. 4 months from a major championship. What's going on......."
Manchester United defender Rio Ferdinand, who earlier revealed he was not interested in taking over the captaincy from Terry, tweeted: "So Capello resigns....what now...."
Who would you like to see succeed Fabio Capello as England manager?
