The Chelsea defender, currently in Los Angeles with his club preparing for the season under new manager Antonio Conte, was part of the England squad that flopped so dismally at Euro 2016.
The 30-year-old, who had captained England under former coach Roy Hodgson, is though determined to fight for his place in Allardyce’s new team.
Cahill, who played in the disastrous and embarrassing defeat by Iceland that saw England crash out in the last 16, said: “I am excited to be working under Sam.
“I’m looking to impress him at the start of the season, if I’m fortunate enough to be involved in the squad.
“I’m looking to keep involved and keep that shirt. I’ve very passionate about playing for my country.
“His appointment is an exciting one for us. It’s going to be a change. It’s going to be interesting to work under him and have his ideas and take them on board.
“It’s down to me to impress him and make sure I hit the ground running so that I am in the squad when he selects them.”
Cahill, who has 47 caps, said: “It’s obviously going to be a change. The manager is going to come in and put his ideas over to us. I’m ready for us to buy into his ideas now.”
