"We think Mason is going to be very important in the second half of the season," Solskjaer said ahead of Wednesday's clash with Sheffield United.
"But it isn't just going to happen by itself because you had a good game and scored. He had a good game against West Ham a while back as well and we expect him to kick on.
"I think Mason has taken steps, he has grown, is more mature and he's been training with Edinson Cavani for half a season now.
"He's learning good habits and whoever doesn't learn good habits from a good professional like him or Bruno [Fernandes], or the players we've brought in, that's a pity. I'm very confident that Mason will chip in with good performances and goals and assists."
