Liverpool caretaker boss Phil Thompson is delighted that Kirkland is ready to step in if needed.
"Chris returned to training yesterday and he trained really well," said Thompson.

The left-sided full back, who suffered a fractured foot earlier this season, picked up a knock to his foot in a reserve clash on Monday, but tests have shown no serious damage.
