I would like to call Arsenal a win or draw the result in the first leg. The worst scenario is Arsenal to lose at home game.
Of course Arsenal must be able to take advantage of the status as a host in the 1st leg. At the moment, the statistics of the two teams are not much different, they are equally strong. I think there will be a difficult game. Even if you remember in the last 16 of UCL in 2016/2017 Arsenal lost by a margin of 4 goals at home or in Germany. After that, it seems that they haven't competed for a long time. Arsenal are in good condition, they still continue to compete as potential EPL champions. As for Munich, it seems they have been focused on the UCL cup. So they will work hard to win in the 1st or 2nd leg. They have the provisions to do that.
This Arsenal vs Munich game is going to be a very tough game to watch,the gunners really want to break that jinx of not getting to anywhere in the UEFA champions league.They believe in themselves now,and since defeating FC Porto,they have been one of the teams favourite for this tittle with their solidity and strong defence set-up.Bayern will really struggle to get a goal at the Emirates stadium in the first leg of the encounter,and thus, I make my predictions,Arsenal 3,Bayern 1.
