The boss briefed the media on Tuesday evening after the club's delegation touched down on Spain's east coast, and the first question focused on whether James Garner or Mason Greenwood would begin the Reds' final clash of the Champions League group stage.
Mourinho responded:
“The kids won't start the match. Garner will be on the bench, and Mason is the protection player, in case we have any injuries.”
The Portuguese had already revealed that Paul Pogba would start the Valencia match, when speaking after Saturday's 4-1 win over Fulham at Old Trafford. In his pre-match press conference at the Mestalla, he explained that other senior members of his squad would deservedly get the same opportunity.
