Prior to the suspension of English and European football, United were on an 11-match undefeated run - equalling the start of manager Ole Gunnar Solskjaer's caretaker reign.
Tuanzebe, in the squad for the derby triumph last month, revealed Solskjaer has placed the emphasis on what United can do to the opposition, rather than vice versa.
He told the Manchester Evening News: “It's unfortunate to have our unbeaten run stopped. The buzz around the changing room was really high, we were going into games really confident.
“We'd obviously spent time on tactics, but we didn't feel like we needed to really spend so much time on the opposition. It was about us and how we played our game and what we needed to do to beat the opposition. So when the focus is constantly on us, we feel good about it and we're just finding ways to beat teams and it's happening. We'd like to get back into that routine again.
“It's obviously a hard time having this stopped but it takes hard work to build that momentum up again on the fly. We have a good squad to do so, we have the belief from the manager, it's upwards and onwards for us right now."
