WATCH: Roma steals late win in Mourinho's 1000th match

Mourinho's milestone game ended in the Roma head coach sprinting down the touchline to celebrate Stephan El Shaarawy's 91st-minute winner with the Giallorossi fans in Monday's (AEST) 2-1 dramatic success at home to Sassuolo.

Former Porto, Chelsea, Inter, Real Madrid, Manchester United and Tottenham boss Mourinho has won 638 of his career matches across all competitions, boasting a 64 per cent winning percentage, to go with 25 titles as a manager.

After Mourinho oversaw Roma's third win from three Serie A fixtures to start the season atop the table, the 58-year-old revelled in the memorable fixture.

"Because during the week I was lying to people, telling everyone this wasn't a special game – perhaps I was trying to convince myself as well," Mourinho, who is in his first season with Roma, said.

"But actually it was – this game had a really special meaning for me. And I am sure I will remember it for the rest of my life, because my 1000th game as a coach was this one.

"I didn't want to lose it, and I was very scared of having that be my lasting memory of the moment. So I was lying to everyone beforehand. It was a very special feeling."

Mourinho – a Champions League, Premier League, LaLiga, Serie A and Primeira Liga winner among other honours – added: "Today it could have finished 6-6 or 7-7, they could have won 2-1, whatever. In the final few minutes Rui Patricio made two or three incredible saves and we missed two or three chances when the goal was gaping. It was an incredible game for the neutral, an absolutely extraordinary match, with so many emotions to it.

"Today I wasn't 58 years old, but 10 or 12 or 14, when you start dreaming about a career in football. Running like I did [down the sideline], I was running like a child. And I apologised to [Sassuolo coach Alessio] Dionisi for that.

"I congratulated him and his players: they played brilliantly. Tonight we won, but if they had won I would not have been able to have any complaints."

It is the first time in Mourinho's illustrious career that he has won the first five games at a club.

"I didn't know that," Mourinho replied when it was put to him. "It's the same as the milestone of 1000 games – I only realised when I was eight or seven short. They are not numbers I'm particularly interested in.

"Obviously I'm happy with the three points, and the great spirit we showed. But we cannot ignore Dionisi and how he must feel: He's a great coach, Sassuolo have a real identity about them – one that comes from De Zerbi, but he has applied his own elements to that. They are a great squad; I realised that as soon as I started studying them.

"These are three massive points for us. Perhaps God decided that I didn't deserve to have a negative memory of this particular game."

Roma, meanwhile, has won six consecutive home games in all competitions for its first time since December 2017 (seven).
