Mourinho’s Spurs travel to the Emirates on Sunday afternoon hoping to stay in touch with the top-four race.
Tottenham are currently seventh in the Premier League – eight points behind fourth-placed Chelsea – while Arsenal are a further three places and seven points behind.
The Tottenham manager told Spurs TV: ‘It’s a pity it’s an empty stadium. We would like to play in full stadiums in these big matches, even away I’d prefer to play in a full stadium, much more adrenaline, much more emotion, I’d prefer that.
‘Anyway, it’s an important game and even if it wasn’t Arsenal, even if it was a ‘normal’ opponent, it would be an important match because we believe we have potential to be in a better position than we are now in the table and it’s a match we have, of course, to try to win.
‘We go in good form, but they are too. I know in the Premier League they are in a position not in relation to their potential, and I focus on the potential, not the position, and the potential is high.
‘They have an incredible squad, they can rotate players, big squad, they play good football. We won the last match against them, but it was a very difficult match to win.’
Tottenham striker Harry Kane hobbled off with a minor knee complaint during Spurs’ Europa League victory over Dinamo Zagreb on Thursday night but Mourinho expects him to be fit for the trip to Arsenal.
‘I hope so and I believe so,’ Mourinho said when asked whether Kane would feature. ‘You know, it’s a big match.
‘I think only a big problem would stop him from being there, which I don’t think it is. Let’s see the reaction tomorrow but hopefully he’ll be fine.’
