Simon Collings reacts to Arsenal penalty shootout drama

For the first time since 2010, Arsenal are into the quarter-finals of the Champions League - and you could almost hear the relief at the full-time whistle.This was a cagey affair, one of few chances, and in the end it came as no surprise that penalties had to decide it.Arsenal were the victors there, winning 4-2, and for Mikel Arteta, this will go down as one of his biggest wins.
