What a mess for Roma, they are playing with one man down currently. Hummels brought down Maroan Sannadi for no reason. It was a reckless tackle and that will cost Roma a lot if they cannot resist the pressure from Bilbao.
Playing with ten men from the 12th minutes till the end of the game isn't going to be easy for Roma. However, if they can seal up their defense, they can still keep the scoreline on 0-0 but how is tgat possible.
Roma wil have to play about 80 minutes with only 10 players and it's hard for them. After several first minutes after Hummels' sent-off of playing panicly, now Roma are back to normal playing and they did not give Athletic Bilbao too much space.
With an advantage of one more player, Bilbao still don't have an easy task, breaking through Roma defense in this match but it's surely very difficulty to play with one player less than a strong opponent like Athletic Bilbao.
Roma's current situation will only force them to play more defensively and maintain not to concede more goals. Roma is ahead on aggregate from the first leg, they must be able to get out of the pressure situation even though it will be quite difficult.
The first half ended with Bilbao leading 1-0. Losing one player early in the first half greatly affected Roma. In the second half, they must make another strategy to be able to get out of the pressure. It's difficult, but their situation has already been like that.
