Bayer Leverkusen returned to the Bundesliga summit with a 3-0 win at Werder Bremen to ensure boss Xabi Alonso enjoyed a memorable 42nd birthday.

Bayern Munich had taken over at the top on Friday night with a narrow victory at Cologne, but Alonso’s unbeaten team provided the perfect response.

An own goal by Olivier Deman broke the deadlock after nine minutes and then it was all about the visitors’ wing-backs.
