Valencia has just recently returned to training from a long-term injury.
“It is difficult to assess Antonio Valencia because he is doing very well, he is in contact training now,” revealed Ferguson.
“He has been taking part in all the sessions, so it is just that decision to play him in terms of his own confidence after such a long time out. It could be two weeks. We are hopeful.
“Park Ji-sung will be another two weeks and Anderson three, depending on how his progress goes because he is over in Portugal at the moment.”
