England manager Roy Hodgson has warned his players that they will be given a "tough test" against Scotland in Glasgow on Tuesday night.
The Three Lions travel to Celtic Park for the friendly in good form, winning their last five matches in all competitions.
However, Hodgson admits that their run could be under threat against the Scots, who have enjoyed a resurgence in recent weeks under manager Gordon Strachan.
"It's an exciting game and we know we will be given a tough test up here," he told reporters. "I don't expect it to be especially physical.
"It will be hard fought I'm sure, competitive. I'm sure each challenge will be competed for but Scotland aren't that type of team and set their stall out to play football like we do."
England come into the match on the back of a 3-1 win over Slovenia in Euro 2016 qualifying.
