Roy Hodgson congratulated former club Liverpool and said it was just a matter of by how much they would win the Premier League.
Jurgen Klopp's men were impressive in a 4-0 victory over Hodgson's Crystal Palace at Anfield on Wednesday.
Liverpool will be crowned league champions for the first time since 1990 if Manchester City fail to beat Chelsea at Stamford Bridge on Thursday.
Hodgson, who managed Liverpool in 2010-11, praised Klopp's side and congratulated them on their season.
"They've been excellent. That moment [they are crowned champions] will arrive soon, quite simply because they are not going to lose any matches – they won't stop winning," he said, via the club's website.
"Their determination and desire in a game when you could have argued they could have taken it a little bit easy because they weren't put under real pressure from us, we didn't see that.
"Even in the last four or five minutes – they are desperately chasing every ball down, winning it back and trying to score again.
"With that type of attitude and desire there is no doubt [the] title is theirs, the big question is by how many points it is going to be, and I can only congratulate them on a wonderful season – two seasons really."
