The Hammers have found their excellent away form tarnished by poor showings at home.
“Their home form is a concern,” said Gale.
“They've got to work out their tactics at home and having spoken to the backroom staff they did discuss pressing Norwich, but they didn't implement what they did on the training pitch.
“They (Norwich) kept the ball for about half an hour without West Ham getting in the game. They've got to work out how to put pressure on teams at home. They are alright sitting back away from Upton Park but the crowd expect more from Slaven Bilic and his side,” he added.
The Hammers have recorded three famous away wins already this season at the Emirates, Anfield and the Etihad, but their home form has been less than impressive.
Leicester City and Bournemouth both left East London with three points, while a late comeback on Saturday stole a point against Norwich.
West Ham’s sole win has come against an abject Newcastle side and there is now little doubt that Slaven Bilic’s men are better suited to playing away.
Pace is now the order of the day for the Hammers and soaking up pressure before launching a counter-attack is a logical tactic given their personnel.
As the home side however, the pressure is on to take the game to the opposition and West Ham will need to adapt their strategy in the coming weeks if they are to build on their sensational away form.
