Tottenham striker Harry Kane says their Champions League hammering of Red Star Belgrade will not count for much if they cannot back it up in the Premier League.
Spurs' rotten start to the season was forgotten for 90 pulsating minutes on Tuesday as they beat the Serbian champions 5-0 in a rousing performance.
"It is always better when you are coming off a win rather than a loss or a draw," Kane said. "But of course we know in the Premier League we are far behind and have a lot of catching up to do.
"Sunday will be a tough game. They have started the season very well so we have to make sure we put in a performance similar to Tuesday.
"Any top game in any top competition there are fine margins between winning and losing and we probably haven't had the rub of the green this season for one reason or another.
"But that is part of the game, we have to overcome that. Performances like this will definitely help but it is about the next one."
