Tottenham Hotspur manager Jose Mourinho believes "football" and "safety authorities" should investigate Stoke City's temporary away changing room which has been described as a pigsty.
Spurs travel to play Stoke in the League Cup quarter-finals on Wednesday (December 23) and Mourinho said he had been sent a video of the changing rooms by a colleague from a team who have played there.
Earlier this month Middlesbrough manager Neil Warnock described the facilities like a "pigsty" that he wouldn't put animals in.
Mourinho said he wouldn't make any further comments on the changing rooms but stated to media on Sunday (December 20) that the relevant authorities should address the matter.
As for the tie, Mourinho said the fact Spurs are playing a second-tier Championship team that does not make their route to the semi-finals any easier.
Spurs and Newcastle United both avoided all-Premier League ties with Arsenal taking on Manchester City while Everton host Manchester United this week.
Mourinho said he was wary of the threat posed by Stoke, who have improved after two seasons of struggle since their Premier League relegation and sit seventh in the league in a closely-contested race for Championship playoff spots.
Spurs were top of the league earlier this month but a point from their last three matches has seen them drop down to sixth and Mourinho is eyeing the League Cup as a chance at redemption.
While the Portuguese has won the League Cup four times, Spurs have not won it since 2008 -- their last trophy.
Mourinho is set to rotate his squad, saying he will play a 'mixture' of his regulars and those who played in the Europa League.
