Howard became a cult hero for US fans as he helped his country reach the round of 16.
The Blues goalkeeper said: "I must be honest I am now looking forward to chilling out and taking a break.
"But I am also really looking forward to getting back to Finch Farm and Goodison and seeing all the guys and the staff and the fans again.
