Four goals, three points and his job secure for now, Slaven Bilic allowed himself to savour a triumphant return to English football and consider what he might achieve as Watford manager.

'Good start, well deserved,' said Bilic, the former West Ham and West Bromwich boss, who seems to be working his way backwards through the alphabet of clubs with an over-inflated sense of where the belong in the grand scheme of things.

At Watford, he is the 16th permanent manager in little more than a decade under the ownership of Gino Pozzo.

The rules of the game are clear enough.

Bilic must win instant promotion back to the Premier League. Shape up as if he might be about to fail and his fate will be the same as his predecessor Rob Edwards, sacked after 10 Championship games.

Like the managerial equivalent of a mayfly, the lifecycle is accelerated at Watford so it's best to enjoy the good days.

Like this one.

'Clean sheet, strikers scoring goals,' said 54-year-old Bilic. 'Stoke is always tough, a team in form, on the up under Alex Neil. Everything was there. Only one game, of course, Buy Bing Ads Account - orvcc.com but something the build on.

'They needed confidence.
They needed belief. You can tell them with words but they needed proof on the pitch and after the second goal, they became completely free to enjoy playing football.

'Our front players and wide players have proper quality so this shouldn't be a fluke.

We can copy and paste this. Nobody did something I didn't expect them to do.'
