Chelsea boss Luiz Felipe Scolari doesn't know whether John Terry will be fit to join up with the England squad after limping out of Saturday's 3-0 win at West Bromwich Albion.
England skipper Terry was named in Fabio Capello's experimental squad for next week's friendly against Germany but could miss out following hospital scans on a foot problem on Sunday.
Terry's club-mates Ashley Cole and Joe Cole have both been omitted from the squad as they remain troubled by hamstring injuries.
Speaking after the victory at The Hawthorns, Scolari said: "I am not the person that can give a good answer, the doctor is but I listened to him and he told John to go the hospital tomorrow and have a scan and see what happens.
"It is an injury but I don't know. If he has the condition I hope he plays because it is the national team and we need to respect that.
"The injury is underneath his foot, a new injury in football. (Juliano) Belletti is the same, Ashley Cole is the same - it's a new injury!"
The victory on Saturday evening was a Premier League record tenth successive away win and put Chelsea back on top of the league table.
Nicolas Anelka scored twice and afterwards Scolari revealed his delight at the recent form of the France striker.
"Nicolas Anelka is happy because he has more confidence, the players and fans believe more in him and give him more chances to score goals," he added.
"He is a very good player, with good skill, good dribbling and a good shot.
"All the games now he scores one or two goals, it is fantastic for us."
