The Red Devils are finding their feet after a shaky start to the season, highlighted by a stunning 5-0 victory over RB Leipzig on Thursday.
Sharpe said: "They've certainly got a lot of talent, but they've started off a little bit slow at home. That could be down to maybe not a great pre-season but they've certainly not started off well at home. Going forward, the players you can see and the players with an attacking-minded game are second to none. They can score goals and destroy teams on the day.
"The question has always been defensive, they've shown in different games with different formations they can cope with the best teams. It can go on to be a good season, even with a stuttery start at home, but I don't see why they can't go and do something big this year."
