When Mourinho was Chelsea manager he entered several war of words against the Reds and manager Rafa Benitez, stirring up many mind games ahead of league, Cup and European games between the two sides.
Now Inter Milan manager, having been dumped by the Blues early last season, Mourinho says he impressed by what he sees at Anfield.
He told the Sunday Telegraph, “It has been interesting watching Liverpool this season. I think they have everything they need to win the title.
“I still can’t understand why they didn’t do it in the last four years. Why wouldn’t they be able to do it this season? Of course they can.
“The manager is good, the players are good, the crowd is unique, the tradition of the club is big, so why can’t they do it? I think they can.”
Mourinho added that the Reds must maintain their focus when the Champions League gets underway again in February and not let their European aspirations become a distraction from domestic ambitions.
“Usually it is when the Champions League starts that they lose their focus on the Premier League,” he continued. “It was like this in previous years when they did very well in the Champions League but they lost too many points in the championship.
“They have already lost 10 points at home by drawing the kind of matches they used to win. Against Stoke, Fulham, West Ham, Hull and Everton it has been two points lost. So if you can imagine that they had those 10 points now, they would be top of the league.”
