Striker Thomas Muller has stressed that Bayern Munich's opening UEFA Champions League Group D opponents FC Rostov aren't an easy team to beat.
Bayern face the Russian outfit at the Allianz Arena on Tuesday in what is widely expected to be a routine victory for the German giants.
If Bayern were to notch a win, it would set a new record of 12 consecutive victories in their opening games of the Champions Leagues over the years.
In addition, it would also move them ahead of Manchester United in terms of extending their winning streak to 13 matches at home in Europe's elite club competition. United won 12 in a row between 2006 and 2008.
Nonetheless, Muller, who has scored 169 goals for Bayern, believes that his side won't be complacent against the Russian visitors.
He told the club's official website, "We know games like this one aren't walkovers but hard work. We certainly won't underestimate anyone. I've rarely seen us approach a match half-heartedly or without focus. The tough competition in the squad does not permit it. None of us can permit it."
