Although Wayne Rooney (hamstring) returned home before the first game in Bangkok and Nemanja Vidic (sciatica) has yet to join the tour, David Moyes' options have been extended by the arrival of Shinji Kagawa, Chris Smalling and Ashley Young in Japan.
The Reds boss could also have Alex Büttner and Jonny Evans back from the minor ailments which caused them to miss Saturday's impressive 5-1 win over the Foxtel A-League All Stars in Sydney.
"Michael Carrick has a tight groin," reported Moyes at Monday's pre-match press conference.
"I expect Jonny Evans to be okay and Alex Büttner to be okay. On the main, we're very close to full strength.
"The three lads [who joined the squad today] probably won't start this game but they'll definitely be involved. Certainly Young and Smalling have been training very hard before flying out here.
"Shinji has mainly been on holiday but he has trained for a few days. We'll get them involved this week."
