The National Tennis Centre is a "white elephant" that has damaged grassroots tennis, according to Andy Murray's former coach.
Mark Petchey believes the money for the facility in London should have been used instead for centres across the UK - including at least one in Scotland.
"It's for a select few and we don't have enough players anyway," he said.
In response, the LTA highlighted a new strategy aimed at boosting participation by increasing spending.
Speaking this week at a tennis course at a school in Paisley, Petchey said an alternative strategy would have meant UK tennis would have now been in a "better position".
