The Gunners missed a number of chances before opening the scoring against the Tigers, breaking the deadlock in fortunate circumstances, which is sure to be used as another example of why video replays are needed.
In the meantime, fans online were enjoying the goal, with some referring it to the 'Hand of Dog' - a punning tribute to Diego Maradona's infamous 1986 goal against England and Alexis's love of his pet dogs.
