United kick-off their Premier League campaign against Chelsea at Old Trafford on Sunday, with Solskjaer confident he has a squad capable of improving on last season's sixth-placed finish.
“Of course Rom has a good record and statistically he's one of the top number nines around when you want to play with that kind of striker, a target man," said Solskjaer.
“But I'm very confident that we'll get goals from Martial and Rashford. Dan James will create and Jesse Lingard will get more.
“It was time now for Rom to go because I think we got a good deal, he's happy, so I think both parties ended that deal as it should be.
“Rom was injured for a while this pre-season and didn't participate, so I just hope for him he'll get a good start at Inter Milan.
“Towards the end of last season we didn't score a lot of goals and Mason Greenwood's pathway would have been a lot more difficult if we had another forward there.
“I believe Mason is going to be playing and involved a lot and when he is he's going to score goals."
