Manchester United boss Sir Alex Ferguson admits Javier Hernandez was disappointed not to see action against Real Madrid.
Chicharito is expected to start on Monday against FA Cup opponents Reading.
"I explained to Javier that Robin van Persie is our main striker and that we want someone to join in from a deeper position," said Ferguson.
"But whenever Javier plays, he delivers. He has 14 goals already, will get ample opportunity and will score more than 20.
"There were a lot of disappointed players.
"Nani and Ashley Young are two international footballers. I find it hard to explain that I have left them out."
