Joao Pedro is adjudged to have been fouled, then offers a few choice words to Jed Wallace, who appeared to bring him down clumsily but with minimal malice.
The Brazilian receives a talking-to for his trouble.
Exactly what Watford would have wanted from the newly-introduced Britt Assombalonga, who breaks away down the left, briefly looks like he might go for broke towards goal and ends up winning a corner on the left.
If his side could keep this in the corner for four minutes, they undoubtedly would.
There will be six minutes of added time, which is a vast amount in the context of a second half that has been full of action and drama.
