The famous fan watched his horse lead for much of the race before falling back to fifth.
Today many sport nuts across the country faced a dilemma - keep an eye on the football or watch the Grand National.
I didn’t. I cannot stand horses and I am really not a gambling man (anymore) so Aintree passed me by this year as if it was one of those holidays you see on the calendar that means nothing to you.
But most footy fans are also into their horses - even those that aren’t get excited when the National strolls into their lives, and many had a flutter on today’s proceedings.
The Wenger critic and Twitter Gunners warrior backed the horse Rocky Creek for the run - but was left disappointed.
However, he could not help but notice some glaring similarities between his horse and his beloved Arsenal…
Indeed Arsenal have led for large parts of the season but 2014 has been a let-down - and defeat tomorrow at Everton and they will be just one point ahead of the Toffees in fourth place.
And just like Piers’ horse it could be a ‘rocky’ race to the finish for Arsene Wenger and co.
