West Brom manager Sam Allardyce says an embarrassing 5-0 defeat by Leeds United shows he has a "tougher challenge" to keep his new club up than he thought:
"I didn't think it was such a tough challenge when we played Liverpool but tonight it's made it even tougher than I thought it was by the way we collapsed," said Allardyce, who has never been relegated during spells in charge of Bolton, Newcastle, Blackburn, West Ham, Sunderland, Crystal Palace and Everton.
"Two sides who just got promoted, 11 v 11 and what a difference between the two.
"We need to make sure we don't dish up another performance like that."
Leeds, who were promoted back to the top flight in July after a 16-year absence, move up to 11th place with 23 points from their opening 16 games.
But Leeds head coach Marcelo Bielsa has warned his side must strive to perform more consistently in the Premier League after demonstrating all of their attacking flair.
"We have only been in this league for 16 games and there are still many challenges and many tests we have to pass before we can legitimately say we belong," said Bielsa.
"We have to keep doing the same and keep doing it over a longer period of time."
