'Where is Coutinho, where is Coutinho...'

Twice Liverpool went behind on the scoresheet in the first half and, if that weren't enough, Watford supporters began to taunt their rival fans referring to their departing playmaker.
Coutinho did not make the Premier League opener against Watford due to a back injury, but the fixture came only one day after the player handed in his transfer request, which was subsequently rejected.
The Brazilian is a much-desired target for Barcelona, and he is also keen on the move away from Anfield. So, with an advantage on the scoreboard, Vicarage Road decided to celebrate by adding insult to injury.
Watford fans singing:
where is Coutinho, where is Coutinho...
