"You have to realise partnerships are built on playing games and we have only had five games," Maguire told United's official club media after the match against his former club.
"We will get better. I will understand him more and he will understand me more.
"There probably will be times when we can do better but we will continue to work hard on the training pitch and that is really important to build relationships around the pitch - not just me and Victor.
"It is really important, as a defence, to keep a clean sheet. At Old Trafford, we need to keep clean sheets to win games, like in the first game of the season [against Chelsea], if we keep a clean sheet, we win.
"We have enough talent in attacking areas to score goals. So, as a back four, as a team, we are really pleased with that."
