Both Lamela and Dembele have had their critics at White Hart Lane, but they have shown their class this season.
Lamela has been one of Spurs’ most dangerous attacking threats throughout the campaign so far, while Dembele has broken back into the team of late.
And Rose said: "Erik Lamela and Mousa have hit some great form. We’re excited but we don’t want to look too far ahead.
“We’ve learned from our mistakes of last season in terms of conceding sloppy goals and now we’re confident that if we score one or two we can win the game. We know we’re always going to score goals with Harry up top and the likes of Christian and Sonny behind him.”
Lamela had a difficult first two seasons at White Hart Lane, after arriving for big money, but he seems to have adapted to the English game now.
Dembele, meanwhile, was on the periphery of the Spurs team at the start of the season, but he has forced his way into the starting line-up in recent weeks.
The Belgian international has scored three goals in his last four matches, and he has enhanced Spurs’ attacking quality even further.
Tottenham have managed to go unbeaten in their last 11 Premier League matches, with their next game coming against capital rivals West Ham United on Sunday.
