Spurs resume their Champions League campaign at a sell-out Wembley Stadium on Wednesday after losing their opening group game against Inter Milan.
"Messi and Cristiano Ronaldo have gone above the norm, when they're scoring 50 or 60 goals a season", said Kane.
"He's definitely set the standard for the rest of us and it motivates me to get even better", Kane said.
Messi has scored 103 Champions League goals, more than any other player, and has eight hat tricks in the competition. At home we have to be strong if we want to progress.
Mauricio Pochettino says he has dreams of one day coaching Argentina before returning to Newells Old Boys as he ruled out ever joining Barcelona. Barca have wobbled domestically lately with two draws and a defeat, to bottom side Leganes, in their last three matches.
"Barcelona are a fantastic side but past year we proved we can beat the big teams, especially at home".
"Barcelona might play better than Real Madrid did last season. It's only about enjoying it, being close, helping the players that are going to face him to stay close and, when you have the ball, trying to have possession, to play in the opposite half, to try to push Leo to play far from your goal".
"If we can get them on their feet as soon as possible, create some chances and take one or two it would put us in a great position".
Spurs have not lost in their last three games while Barcelona's recent form is uncharacteristically poor with no win in their last three.
But the England midfielder, like Hugo Lloris, will be missing against Barca with Christian Eriksen, Mousa Dembele and Jan Vertonghen all doubtful.
