It will be difficult for City to eliminate Bayern Munich I doubt if this will be possible, Real Madrid qualifying is sure because they will definitely win Celtic to qualify to the next round so difficult game there will be Bayern Munich vs Manchester City one of this big team will definitely be going home I believe one of these team here between Manchester City, Real Madrid and Bayern Munich will be playing this season UEFA Champions league finals despite they qualify to the knockout stage I think they are gradually gaining back form unlike when they were playing badly.
The draws hasn't yet been determined as it stands until Friday before every opponent will know whom to face. Real Madrid Vs Celtic isn't sure. Real Madrid might likely be paired with Bayern Munich or Manchester City. It's till Friday before we will know which team that faces the other.
