Hector Bellerin has been waiting almost five months to get back at Troy Deeney for his comments after Watford's shock victory in October, and he took his chance on Sunday.
With Arsenal holding a 2-0 lead at the Emirates, Deeney was handed the chance by Martin Atkinson set up a nervous finale for Arsene Wenger's men.
The referee awarded a penalty after Roberto Pereyra was brought down by Ainsley Maitland-Niles. Deeney, who scored from the spot in October's 2-1 win over the Gunners, stepped up, and was denied by Petr Cech.
After stunning Arsenal in that ear-season encounter, the Hornets striker went on to make headlines slating Arsenal's lack of 'cajones' and inferring Bellerin's judgement on a potential Arsenal spot kick was restricted by his 'long hair'.
