He said, “He needs to be careful – everyone needs to be careful – and know the right way,” said the Portuguese Silva.
“Everybody at the club knows the rules and their obligations as a professional.”
“What we are talking about is one situation in September,” added Silva, who refused to reveal whether Watford would discipline the Nigerian striker.
One would hope that Success who joined the Hornets for a then club-record fee of £12.5m from Spanish club Granada in August 2016, signing a five-year contract would adhere to the warning as his future with the club maybe put on the line.
Isaac success has yet to future for the Premier League side this season. He managed just one goal from 19 games last season, netting against Bournemouth over a year ago. However, he now faces eight weeks out with injury following a knee injury sustained in training.
“We expect six to eight weeks,” said Silva. “It’s a knee injury, a problem he had in one session here.”
“It was a normal situation and looked nothing special at that moment but after examinations, the problem is bigger and now we need to wait for him.”
Success’ sole appearance for Watford this season came as a second-half substitute in their 3-2 defeat by Bristol City in the Carabao Cup in August.
