On 9 March 2010, Nicklas Bendtner scored a penalty to seal his hat-trick in a 5-0 Arsenal win over Porto in the Champions League, as the Gunners confirmed their place in the quarter-finals by overturning a first-leg deficit.
It has taken 14 years and three days, but Arsenal are back in the Champions League last eight - with Porto, penalties and a second-leg comeback once again in the script.
This time, it was not a penalty scorer who took the headlines but a penalty saver, with David Raya denying Porto twice in a 4-2 shootout victory.
