Playing a draw at home is not always considered bad if Arsenal can provide a better game in the second leg (away match). Of course, Bayern Munich will likely be the favorite at home, but Arsenal is a good team who will most likely also win the second leg.
I agree with you. It is not always bad to have a draw at home, there is a chance to get a win in away match.It is true that Bayern Munich will take an advantage in a home match, but they don't automatically win the match. Sometimes, playing away makes a better motivation for a team. So, Arsenal still has a chance to qualify for the next round, they aren't eliminated yet.
Manchester City and Arsenal both ended the first leg of the Champions League quarter-finals with a draw. They have good form to hope for a ticket to the semifinals, but Real Madrid and Bayern Munich also have the same chance in the second leg. This match will be very interesting of course, that's because all four teams still have a chance.
Surprisingly, this match also ended with a draw. I guess Real Madrid will win the match, sadly they played worse in the second half of the match. Man City will be more comfortable for the Leg 2 because they will play at home. However, Real Madrid is a very experienced team in UCL. Everyone knows that this team will always try until the end of the match. So, I still favor Real Madrid to win against Man City in Leg 2. If they can make a stronger defense, they only need to score 1 goal and defend it until the match is over.
