Manchester United boss Ralf Rangnick admits Edinson Cavani has been reluctant to play from the start due to injury concerns.
Cavani came off the bench to score the equaliser in Monday night's draw at Newcastle.
Rangnick revealed on Wednesday: “Actually over the last few days, I was also considering playing him from the start.
"I spoke with him yesterday and the day before yesterday and he didn't feel comfortable to play from the beginning because he didn't know how fit he was but today after being 1-0 down at half-time, it was clear to me that we needed to take more risks, to change something and that's why we decided to bring on him and Jadon [Sancho] at half-time."
