Manchester City vs B. Monchengladbach prediction (Over/Under)

Manchester City is in great shape, and considering the various games of other teams that I watch; for now City is one of the best teams in Europe. Last weekend, despite some problems such as the absence of Aguero; they won on the road 2-1 against Manchester United. The team is still unbeaten since the start of the new season, including two games by UCL; against Steaua. Borrussia has a decent team, especially in attack, and more than 12 games on the road marking at least one goal in every game. Last weekend the team lost in the Bundesliga 3-1 on the road against Freiburg. These are two teams that have offensive characteristics, particularly Manchester City, for this game Aguero is back and this adds more strength in attack. Considering also that Borussia is very good in attack, but defensively has some problems; I think it will be a game with great possibilities to happen many goals as last year in both games between City vs Borussia happened at least 3 goals.
