Bayern Munich cruised to a 4-1 win over Arminia Bielefeld on Saturday, Robert Lewandowski helping himself to another couple of goals.

Robert Lewandowski maintained his magnificent goalscoring form as Bayern Munich eased to a 4-1 Bundesliga victory over Arminia Bielefeld on Saturday.

Lewandowski scored four times in Bayern's 4-3 win over Hertha Berlin in their last match before the international break and struck twice for Poland in a victory over Bosnia-Herzegovina in midweek.

The prolific striker took his goalscoring tally for the season to nine goals in seven matches with a first-half double at Bielefelder Alm after playing a big part in Thomas Muller's opener.

He then set up Muller for Bayern's fourth as the champions, who conceded to Ritsu Doan's low drive before losing Corentin Tolisso to a straight red card, made it four wins in a row in all competitions and climbed into second place.
