The young Belgian goalkeeper made his United debut in Saturday's 2-0 win against Sunderland.
Schmeichel said on Sky Sports: "You think about the goalkeeping that we have had over the last couple of years and how many goals we have conceded from errors from goalkeepers. What was it, nine errors already this season?
"That's a lot, it's too much. I go back to when I played - my instruction was - and I think it was the same think with (Edwin van der Sar) and David De Gea, we had to save the team 10 points a season, not give them away.
"That's what we have got used to in the last couple of years - goalkeepers giving goals away, and therefore we're losing points. So it's nice to see first of all a clean sheet, then a really good and solid goalkeeping performance."
