VIDEO: Lewandowski scores clinical header after breaking Arsenal's offside trap

As one of the very best strikers currently consuming oxygen, Bayern Munich superstar Robert Lewandowski doesn't need much of an opening to find the back of the net.

Somebody apparently forgot to make Per Mertesacker aware of that fact, as Arsenal's erroneous attempt to play an offside trap in the early minutes of Wednesday's Champions League match left the imposing striker all alone inside the penalty area, and saw Lewandowski - who timed his run to absolute perfection - flick a header beyond Petr Cech to open the scoring.

The goal was Lewandowski's 26th in the Champions League since the beginning of the 2012-13 season, putting him second in that time behind only Cristiano Ronaldo (43).
