Player to watch: Antonio Nusa, RB Leipzig -- With six assists and four goals in the Bundesliga this season, the 21-year-old Nusa has the look of a player who may be establishing himself as one of Europe's best young attackers. Prove what he can do against Matheus Nunes and the rest of the Manchester City defense, and the Premier League clubs will surely be clamoring. -- James Benge Man of the match: Erling Haaland, Manchester City -- This is one of those games when the Norwegian striker delivers. He already faced RB Leipzig multiple times when he played at Borussia Dortmund before moving to Manchester City. Haaland, who has scored four goals so far in the two Champions League matches played this season, needs to lead his team to victory after a disappointing defeat against Brighton over the weekend at the Etihad Stadium. -- Francesco Porzio
Prediction: RB Leipzig 0, Manchester City 3 -- RB Leipzig have started the season in a rough patch, which makes a meeting against Manchester City very untimely for them. Enzo Maresca's side are still a work in progress, but that is unlikely to be an issue on Wednesday, when they should be able to overpower their opponents with relative ease. -- Pardeep Cattry
Best bet: Erling Haaland to score first (+290): After failing to score against Brighton over the weekend, Haaland saw a seven-match scoring streak come to an end in Premier League play, and what better way to move on from that than by continuing his Champions League one. While Haaland didn't play against AEK Athens, he has four goals in only two Champions League appearances and will be a focal point yet again in an away trip to face the German side, and as City looks for a fast start, the Norwegian will be able to provide it. -- Charles Booth
