Isaac Success has been criticised by his head coach Javi Gracia for behaving badly in Watford's 2-1 defeat against Tottenham Hotspur at Wembley.
The Nigerian was booked for punching the ball out of the hands of a ball boy with the Hornets trailing in the game.
Immediately after the match, Gracia would not pass comment on the incident having not seen it, but a day later, after watching a replay, Gracia said Success needs to improve his behaviour.
He said: "I don’t like to see that from my player with a boy. We have to look after they boys always and it's not a good reaction.
"I'm not here to educate the ball boys about what they have to do, it's not my job. What I can say is we need to improve our behaviour next time."
Following the game, Gracia said he was disappointed to have lost but that he is pleased to see that his side believe they are capable of competing with anyone in the league.
He said: "Always when you lose you are disappointed. In this case, after trying to win the game and conceding the goals in the last ten minutes, it was difficult for us.
"Against Tottenham, it’s a good moment to win against them and after, all of us were disappointed.
"It’s a good sign for us to feel that, to feel the players believe we are able to beat all the teams and it was a good reaction from my players."
