West Ham will decide Julen Lopetegui's short-term future by the weekend.
Lopetegui is under huge pressure following Tuesday's 3-1 defeat at Leicester and sources say the manager's future hinges on a club board meeting to be held later this week.
Brought in on a two-year deal to succeed David Moyes in the summer, the former Spain and Real Madrid coach arrived at the London Stadium amid huge expectation.
West Ham spent more than £120m on nine new players in the belief Lopetegui could steer them towards a return to Europe after missing out last season for the first time in four years.
