Liverpool boss Roy Hodgson has voiced his concern at the form of England right-back Glen Johnson so far this season.
The 26-year-old has only featured twice since the end of September due to injury problems, but Hodgson is concerned by what he has seen when Johnson has been involved.
He told reporters: "He's the England right-back and, if he plays like that, one would expect him to come back in when he's fit.
"But then he'd have to play like the England right-back and up to now, to be quite frank, he's not performed - very often at least - to the level I'd expect of him.
"You would have to ask him 'do you think you're playing at top form and are you playing like the best right-back in the country for your club?'.
"If he says yes, obviously we will have to agree to differ and if he says no, then you'd have to ask the question 'why not?'."
