The 20-year-old, who is desperate to leave the club this summer, cited illness for his absence on Wednesday and Thursday but reported for duty ahead of the preseason tour.
Raheem Sterling has reported for Liverpool preseason training after calling in sick twice earlier this week.
The winger was absent as the first-team squad returned to Melwood on Wednesday, citing illness, before repeating the claim on Thursday amid ongoing speculation over his future.
Sterling told Brendan Rodgers of his desire to leave Liverpool at the end of last season, with Manchester City since having two bid rejected and the club preparing a third.
