Tottenham boss Juande Ramos is continuing his search for the right goalkeeping coach to work with Paul Robinson.
"We have been looking ever since my first day," said Ramos.
"We've been trying to resolve it."
High-profile errors led to Robinson losing his England place to Scott Carson for the final match of Steve McClaren's reign.
"I don't know all the English keepers that well to make that assessment," said Ramos.
"We are very happy with Robinson and what he brings to the team and how he's helping his team-mates."
Ramos believes the whole team needs to take collective responsibility for the goals conceded.
"I am worried that the team concedes so many goals," said the Spaniard.
"The whole team gives away goals, not just Robinson."
