He insists sending the pair to Inter Milan was the best decision for all concerned.
Solskjaer told Sky Sports: "In one-off games, you think we could've had a number of extra players with experience. Alexis and Rom are goalscorers and good players, but at the moment, we made those decisions and they were the right decisions.
"That's the only way you've got to look at it. All the players here want to give everything for the club and for the shirt - that's a big thing.
"Every day that they come in training, and every day that they put the shirt on, they're going to give everything that they have. So you can't really say, 'oh I wish I didn't do that'.
"Giving a couple of the lads the chance to show themselves, maybe it was a little bit too early for a few of them. But Mason Greenwood has stepped in and scored a couple in the midweek games, so it's a great experience for them.
"We know we haven't had the results that we wanted, but I wouldn't have kept the players we sold. It was the right decision."
