Solskjaer sat down to speak to the press after the victory, and was asked for his opinions on whether Rashford can be a 25-goal-a-season forward.
But the Norwegian dismissed the question outright.
"Now is not the time to think about how many goals you're going to end up with," replied the Manchester United boss.
"As long as you concentrate on the next job in hand, training tomorrow, of course he only played 30 minutes. There's one step at a time, if you get too far ahead of yourself you're going to lose focus.
"Marcus has showed he can keep focusing on what's important on and off the pitch at the moment. He did really well today coming off the bench."
