Jose Mourinho admits it is going to take something extra special to crack the 86-game unbeaten home record set by his Chelsea team.
Liverpool's long run without a Premier League defeat at Anfield came to an end after 68 games, stretching over almost four years, before Burnley's 1-0 win, on Thursday.
Chelsea, however, did not lose a single league game at Stamford Bridge from February 2004 until October 2008, a sequence more than covering Mourinho's first spell at the West London club.
'The records are there to be broken, even the most incredible ones in so many sports,' said the Portuguese, now in charge of Tottenham. 'There are some records that you look to them and you feel that it is impossible for somebody to do it.
'What Liverpool did is amazing and very, very difficult to achieve. Our record from Chelsea is still the record and is very difficult for somebody to do better than that. But congratulations to Liverpool for the amazing run they had by not losing a Premier League match at home for so long.'
Avram Grant was in charge when Chelsea's record was ended by Liverpool.
Mourinho did not lose a Premier League game at home until deep into his second spell at the Bridge, a defeat by Sunderland in April 2014.
Much of his 'Special One' mystique was built around the invincibility of his teams on home soil but the Spurs boss fears bigger teams are increasingly vulnerable to shock results.
'What was almost a scandal, years ago, is not anymore,' said Mourinho as he prepared his team for Monday's FA Cup tie at Wycombe. 'Any team can go to any stadium and get a result.
'The teams considered with less potential are not like that as much anymore, these clubs and professionals deserve the credit.
'I don't open my mouth anymore and say 'wow, what a crazy result.' There are no more crazy results.
'Every team, even those with the objective to be champions or top four, I am not surprised if these big teams have a run of matches where confidence drops a bit because of bad results.
'The reality is that nothing is eternal. Not consecutive victories and not consecutive defeats. Always the next matches are open with open results.'
