(Reuters) - West Ham United hope to continue their recent giant-killing feats when they take on Manchester City at the weekend, but manager Slaven Bilic does not expect Manuel Pellegrini's side to suffer a dip in confidence after losing to Juventus in midweek.

The Hammers have arguably been the enigma of the early going so far, with disappointing home defeats by Bournemouth and Leicester City offset by impressive away wins over Liverpool and Arsenal.
