Tottenham chairman Daniel Levy has lambasted contractors working on their new ground in a bid to finally attain a full safety certificate, according to The Sun.
The £1billion stadium was allowed to open in April when Haringey Council made concessions and allowed the club temporary clearance to play at the stadium until the end of the season.
That permit has now expired and Spurs must get important works on electrical and safety systems finished or they will not be granted a full licence to open before the start of the 2019/20 season.
It is claimed Levy put contractors under substantial pressure at a recent meeting, warning that the club will not be able to get a certificate unless all work was completed.
The club were told that in its current condition, Haringey council will not sign off a full permit for the stadium.
It means the club are now having to apply on and event-by-event basis to host big large crowds, including showing their Champions League final clash with Liverpool there when they hope for a 62,000 sell-out.
Levy was determined to make it clear that not one workman would be allowed to remain on site when the council inspectors visit or the certificate will not be issued.
The fear is that Haringey Council, having allowed the temporary certificate in lieu of more work being carried out across the site, will not be so lenient when they inspect over the summer.
Tottenham insist there is no cause for alarm, and that issues they are experiencing are similar to those encountered when other large buildings are opened.
A club spokesperson said: 'It is normal to be granted a game by game safety certificate at a new event based venue and it was always the case that we would work in this way when we first opened.
'This gives the local authority time to work with the Club to review safety procedures and crowd flows.
'None of the outstanding works are build related - they are related to functionality and integrating them into our building management system, all part of making this the most technologically advanced stadium around.
'The trade teams along with our stadium ops team have met with the Chairman every Tuesday for the last three years.
'The desire now is to finish out the integration works in order to secure a permanent safety certificate. It does not impact, in any way, our ability to host events.'
