Tottenham boss Jose Mourinho says his side "have problems I cannot resolve myself" but does not believe Spurs are in crisis after losing at West Ham - their fifth defeat in six league games.
Michail Antonio and Jesse Lingard scored for the hosts before Lucas Moura pulled one back.
"I wouldn't say crisis," said Mourinho when questioned about Spurs' form.
"I would say a bad, a really bad, run of results. That is obvious. We're losing too many matches."
Newspaper reports on Sunday suggested Mourinho's job could be at risk if his team failed to win at London Stadium.
