The morning after Spurs’ 3-1 loss to the Blades, Arsenal’s official Facebook page posted a video of their dramatic FA Cup victory at Sheffield United.
It contained the caption “It’s not easy beating Sheffield United at Bramall Lane. Here’s a reminder of how it’s done” with a smirking emoji.
Mourinho was asked whether he had an opinion on the post, which he was clearly well aware of.
“Not really, I think if they were top of the league or fighting for top four in a really good moment they wouldn’t enjoy the problems of others,” he said.
“You only enjoy the problems of others when you are also in trouble.
“In the end it says more about them, they don’t have much to celebrate they have to get every opportunity to do it. They are in a very similar situation to us in the table.”
He added: “I don’t like to connect the club with some post or tweet. Maybe I am wrong, maybe I am right, but the person that did it probably did by themselves.
“I don’t believe that was Arteta that posted, I don’t believe it was Xhaka or another captain that did it. It was probably some guy that was for three months working from home. No problem at home, but we will be waiting for them.”
Tottenham host Arsenal in the north London derby on Sunday but Mourinho has no interest in just looking to finish above Arsenal.
“To be the champion of north London means nothing for me because I think you have to be much bigger than that and have much more ambitions than that,” he said, “But I always look to the rivals of my clubs with different eyes.
“As you know I have been in so many big clubs with so many special rivals so I don’t hide that Arsenal in this moment is a very special rival. Yes I would like to finish in a better position in the table than them but again I want my team to be bigger than that.
“I want my club to feel bigger than that. I understand that for the fans it is a special rivalry and what is special for the fans is special for me and I want it to be special for the players.”
Mourinho was disappointed with his team’s reaction to the controversial VAR decision that ruled out Harry Kane’s first half strike, questioning their mentality when things go against them.
When asked what he had done about that in the days since, the Spurs boss said: “I like the players, I keep saying I like the players very, very much. I believe in the players.
“I cannot promise we are going to win on Monday because football is football but I can promise you that the players are going to have a different attitude, I want to believe that.
“For some reason, for so many months, a couple of years, the team is showing, especially away from home, lots of weaknesses at this level.
“I think there are reasons for that, but I like the guys, I believe in them, I keep saying they have great potential as players.
“After the game it is normal that even trying to keep the emotional balance, it is always normal that the coach doesn’t control it 100 per cent and one opinion, one criticism comes out.
“I believe in the guys and I am waiting for an answer and I am waiting for the next matches, some away from home with similarities to the Sheffield game, I am hoping that the boys can show a different face.”
He added: “I think at home we also have our problems. I am not saying that, but especially away from home, we go to the records and we realise the results have been really, really bad.”
