Tottenham boss expressed frustration as the game, which has now been called off, remained in doubt hours before kick-off
Spurs were due to host Fulham on Wednesday, having won a 1-1 draw against Wolves on Sunday as they continue through the holiday season.
However, the status of the game was on hold after Fulham was hit with a number of positive coronavirus tests before the league finally postponed it hours before kick-off.
The game is the second in days to be postponed due to coronavirus, with Manchester City’s meeting with Everton canceled on Monday after the first confirmed a series of positive tests.
The news comes after Fulham manager Scott Parker missed the team’s goalless draw with Southampton Boxing Day after a member of his household tested positive for Covid-19.
Fulham was due to cross London for the game on Wednesday, but that trip was eventually called off.
With the game still on hold hours before kick-off, Mourinho took to social media to express his frustration with all the uncertainty surrounding the game and the decision to play or not.
“Match at 6 p.m. … We still don’t know if we’re playing,” he posted on Instagram alongside a video of his staff glued to their phones and television. “Best league in the world.”
In recent days, there have been calls for the Premier League to take a hiatus as the league faces an increase in the number of coronaviruses.
Premier League announced on Tuesday highest number of Covid-19 cases since the start of weekly tests, with 18 people who tested positive.
In response to this increase in positive cases, Sam Allardyce and Nuno Espirito Santo have said they believe the league should take a hiatus until the testing numbers come down.
The league broke throughout the holiday season, with teams playing three games a week during the typical holiday crisis.
