Bayern Munich started their Bundesliga campaign in emphatic fashion as they romped to a 5-0 victory over Hamburger SV at the Allianz Arena on Friday evening.
Costa and Vidal make league debuts
Medhi Benatia heads Bayern in front
Lewandowski doubles Bayern's lead
Müller bags quick-fire brace
Costa nets Bayern's fifth late on
Bayern went into the first-half break with a slender advantage following Mehdi Benatia's headed goal, but showed a ruthless edge in front of goal after the half-time interval.
Robert Lewandowski doubled Bayern's advantage with a well-time shot early in the second half, before Thomas Müller netted two goals in quick succession to put the result beyond any doubt.
Despite boasting a healthy lead, Bayern didn't ease off in the closing stages and rubbed further salt in the wounds of visitors as Douglas Costa pounced on a defensive slip before slotting past the onrushing keeper with three minutes remaining.
The visitors started the match on the front foot and threatened Bayern's goal after just three minutes. However, debutant Sven Schipplock was unable to fire HSV in front after being teed up by Lewis Holtby, as his effort was easily kept out by Bayern keeper Manuel Neuer.
Bayern boss Pep Guardiola fielded an attack-heavy formation once again, though, and it didn't take long for the hosts to exert their dominance.
Arjen Robben failed to guide his header on target in the seventh minute following a lovely ball over the top from David Alaba, while captain Phillip Lahm saw his goal-bound effort blocked by the HSV defence a few minutes later.
Another Bayern opening arrived in the 21st minute as Robert Lewandowski's flicked header looped over goalkeeper René Adler before landing on the roof of the net
However, following a sustained period of intense pressure, Bayern finally got the breakthrough they were looking for just moments before the half-hour mark. Xabi Alonso sent in an inviting cross direct from a free-kick and Benatia raced in behind the defence before heading home past the flat-footed Adler.
The flood gates almost opened as Bayern surged forward in search of a second, but efforts from new signing Douglas Costa and Alaba failed to beat Adler in the Hamburger goal.
The Bavarians remained firmly in control as the half progressed, although some tight marking from the visiting defence restricted the effectiveness of Bayern's wide play.
There was one more chance for the hosts on the stroke of half-time, though, with Alaba firing just inches wide of the top-right corner after latching onto a botched clearance.
Guardiola's men redoubled their efforts after the break after failing to show a cutting edge in front of goal in the opening 46 minutes.
They made their intentions known early on, with Alonso forcing Adler into a low, diving save with a curling free-kick from a dangerous area.
Having produced a somewhat subdued performance in the first half, Robert Lewandowski justified his inclusion as he struck home in the 53rd minute. HSV full-back Matthias Ostrzolek managed to beat Muller to the ball, but his header went only as far as Lewandowski, who lashed the ball home from inside the area to double the home side's lead.
Hamburg, who had spent much of the second stanza camped in their own half were unable to muster a response as a dominant Bayern kept the visitors pinned back in their own half.
A sustained period of pressure paid dividends for Bayern as Müller made it 3-0 following a glancing header at the near post on 69 minutes.
HSV were still reeling from the third goal when Müller struck again four minutes later, the Germany international pouncing on a through pass from Lewandowski before rounding the keeper and firing into an unguarded net.
Not content to miss out on the action, Alaba again tried his luck from range in the 79th minute, but Adler was alert to the danger and did well to keep out the effort with a sprawling save.
However, there was nothing Adler could do to deny Bayern a fifth in the 87th minute, as Ostrzolek lost his footing in a dangerous position, allowing Costa to nip in and fire into the bottom corner.
