Jack Wilshere dismissed the agent who guided him through the early years of his career after being overlooked for a new Arsenal contract 12 months ago.

Football Insider has learned that Wilshere parted with Simon Bayliff and joined with David Beckham’s former adviser Terry Byrne due to the midfielder’s frustration that he missed out in the club’s extensive round of contract renewals last year.

The Arsenal talisman was particularly frustrated that fellow midfielder Aaron Ramsey was given a new £110,000-a-week deal that lifted the Welshman above Wilshere in the roster of earners at the club.

Both players had been among a five-man group of British stars, that also included Alex Oxlade-Chamberlain, Kieran Gibbs and Carl Jenkinson, who had signed deals in December 2012 that ran until 2018.

Arsenal rewarded Ramsey for an outstanding season with an improved deal last March at a time when he was sidelined with a long-term thigh injury. They also handed improved contracts to Santi Cazorla, Olivier Giroud, Per Mertesacker, Laurent Koscielny and Tomas Rosicky.

Wilshere subsequently sacked Bayliff and joined forces with Byrne, who set up his own management agency 10Ten last year after managing Beckham’s playing career.

Byrne also represents former players Pele and Glenn Hoddle but Wilshere is his star client.

The England international’s future is on the agenda following a campaign in which injury has restricted him to just 16 Arsenal appearances and reports have linked him with a possible summer move.

As revealed by Football Insider on Monday, Arsenal are preparing to open new contract talks with the midfielder at the end of the season.

The Londoners want to demonstrate their commitment to Wilshere even though his current agreement has three years to run, with manager Arsene Wenger retaining full faith in the Gunners talisman despite the series of serious injuries that have stalled his progress since his breakthrough 2010-11 campaign.

The England midfielder was set to make his long-awaited comeback last month after undergoing ankle surgery in November but it was put on hold after he felt pain in his troublesome right ankle.

Wilshere is now back in full training and closing in on a first-team comeback after completing two matches for the Under-21s in the last week.
