Sam Allardyce's son admits he will be devastated if he has hindered his dad's chances of becoming England coach.

Bolton boss Sam Allardyce is promising to launch a full inquiry into a controversy surrounding the proposed new signing of 30-year-old Idan Tal.

Son Craig, a players' agent, has been implicated in the transfer of the midfielder from Maccabi Haifa.

He said: "I am devastated about what is being said. I have conducted myself properly in the transfer of Idan Tal."

Craig Allardyce has vowed to avoid any Bolton dealings while his father, thought to be in the running for the England job, is boss.

Tal has signed a three-year pre-contract agreement with Bolton but agent Ronen Katsav plans to sue the player over claims he reneged on a previous arrangement.

Bolton boss Allardyce yesterday claimed the club had done nothing wrong but added: "We will cover all angles, because it is me and my son, and make sure it is 100% OK."

Craig was quoted in the Daily Express: "If in any way I have hindered my dad's chances of becoming England coach then I would be devastated.
