Three Manchester United players, who have been absent of late, were spotted in the final training session ahead of our Europa League tie at Viktoria Plzen.
The Reds worked at Carrington before the flight to Prague, in advance of the 17:45 GMT kick-off on Thursday.
Centre-backs Jonny Evans and Victor Lindelof could be available again to increase the options open to head coach Ruben Amorim, as he plays a three-man defence.
The experienced campaigners have been missing, with Evans only appearing once for the new boss, in his opening game at Ipswich Town, and Lindelof's last game coming against PAOK in this competition.
