The Cameroon international joined United from Inter Milan this summer as a long-term replacement for David de Gea.
Making an early impression during United’s pre-season tour of the US, the goalkeeper ran out from his goal to berate Maguire during a 3-2 defeat to Borussia Dortmund in Las Vegas, unhappy with a sloppy pass from the centre-half.
Onana was recently criticised over the incident by former Liverpool defender Jamie Carragher, who suggested the goalkeeper ranted at his teammate in an attempt to endear himself to United fans ahead of the new campaign.
Speaking ahead of United’s group stage opener against Bayern Munich, Onana was quizzed on whether the incident has been overblown by the media.
He told reporters: ‘No, Harry is a very good guy, I have a good relationship with him, I even spoke with him this morning before we took off for Munich.
‘What happened there, I already explained straight after the game.
‘I don’t think we have to give importance to what happened because are big guys and what happens on the pitch stays on the pitch and we definitely have a good relationship.’
Onana returned to action with Cameroon during the September international break having retired from international duty late last year following a disagreement with manager Rigobert Song.
Cameroon sealed their place in January’s Africa Cup of Nations in that win over Burundi with Onana set to miss a string of games for United if he is selected in the squad for that tournament.
Onana was quizzed on his international future on Tuesday in Munich but insisted no decision has been made.
‘If am called up, I don’t know if I am going to be called up so we can’t speak about things we don’t know.
‘Let’s see what is going to happen in the next month but we are here to play against Munich, an important game for us so all the focus is on that game tomorrow.’
