Morgan asked fans to send him questions for an @EventMagUK column and Manchester United fans took the opportunity to remind him of last weekend's result while an Arsenal supporter chipped in with a question about the Gunners' trophy drought.
Several Arsenal stars were not at their best during the Old Trafford fixture where former Gunner Robin van Persie scored the only goal of the game in a 1-0 win for the champions.
Morgan took a lot of stick at the time and while there were some sensible questions for him to answer and use for his column, there were a couple of fans who just couldn’t help themselves.
Hi Piers! Did you know that 22 people have been killed by vending machines since Arsenal last won a trophy?#AskPiers— Since AFC won a cup (@afc_trophy) November 12, 2013
