If Bayer Leverkusen are to be our toughest test in this group, then we can safely assume our progress is a given - the Germans have been hugely disappointing and have barely gotten out of their own half as Manchester United dominated to earn a 1-0 lead at half-time.
Wayne Rooney got the goal, volleying home a Patrice Evra cross to put United in the lead, although the visitors appealed heavily for an offside on Evra.
United had chances to score later, Shinji Kagawa scything one ball across an open goal before later going close with a low curling effort. Wayne Rooney fired in a dipping free-kick which went just wide, and right before the whistle Robin van Persie cut inside but miscued his left-footed effort.
Most impressive of all, and probably thanks to Fellaini (although Kagawa has been excellent) is that United have looked like an actual side who can pass and defend and tackle in midfield. They look like a team that doesn't have a big problem there, and they've completely dominated, with Bayer barely even looking like creating a chance.
Our pressing has been quite fierce so that could all tail off, but it'd be a surprise were Bayer to improve that much.
