Swansea's first-team coach raved about Tottenham on Sunday afternoon - just as Watford's did earlier this month.
And Curtis feels Tottenham are the best team they've faced - talking up their chances of winning the title.
The Swans first-team coach told Sky Sports after his side's 2-1 defeat: "Yeah, absolutely [Tottenham can win the title] especially when you see them close at hand there. I think they've got every opportunity.
"I would have to say they are the best team we have played this season. I thought they were terrific and credit to our boys for staying in the game as long as we did.
"We had given ourselves an opportunity to get something out of this but probably more credit to Spurs that they kept on coming and it was probably difficult to keep them out in the end."
Do the quotes bring about a sense of deja vu? If so, it's because Watford boss Quique Sanchez Flores said virtually the same thing about Tottenham when his side lost 1-0 at White Hart Lane.
As reported by the Independent, the Spaniard too raved about Spurs' relentlessness, the fact they wouldn't give up and claimed they are the best team Watford have faced.
Were it not for Leicester City, the Premier League table would also have Tottenham at the top.
If there's one thing the Foxes do better than anyone else, it's how quickly and directly they can turn defence into attack. In many, many areas, though, Mauricio Pochettino has his side operating at a level higher than anyone else.
