Newcastle United manager Eddie Howe admits defeat at Brighton shows his team is in trouble.
The Magpies were beaten 3-1 thanks to an Evan Ferguson hat-trick for the Albion.
After picking up a measly three points from the first four games of the season, Howe knows his team must find its cutting edge.
"It's never been lost on me how difficult the Premier League is," he said post-game.
"I know how tough a league it is, it's ruthless, so if you get your focus swayed, you're going to have big problems - I don't think our focus has been.
"We've tried to very much concentrate on our next match, that will always be our focus and we're determined to be successful in the league this year and win as many games as possible.
But we know the demands placed upon us are going to be extreme so this is a warning, I think, that we can't be swayed and the Premier League is a very tough division. We've lost three in a row and we have to take responsibility for that. It's important that I don't over-react."
