Southampton and England goalkeeper Fraser Forster has told his international teammates to expect a "special" atmosphere at Celtic Park when they face Scotland there next week.
The former Hoops stopper, who is in line for a start in the friendly fixture, is expecting the home support to treat the match like a competitive game.
"If any of the England lads have not played at Celtic Park, I can assure them it will be a very special occasion, and not quiet," he told reporters.
"It's a stadium with a fantastic atmosphere, and with 60,000 people there for Scotland vs. England it will be a very different experience."
Forster, whose club have the best defensive record in the Premier League, could earn his third cap against Scotland.
