Manchester United boss Erik ten Hag was tightlipped on Marcus Rashford's absence before their FA Cup win at Newport County.
Rashford missed the tie after it broke in the morning he had spent the week in Belfast partying before missing Friday's training session.
"He reported ill. The rest is an internal matter and I will deal with that," said Ten Hag.
Questioned further after the 4-2 win, the manager replied: "It is an internal matter."
Asked whether that posed more questions than answers, Ten Hag added: "For you, not for me. It is an internal matter and I will deal with it. We will deal with it. I will deal with it."
