Arsenal boss Mikel Arteta admits Tottenham now boast one of the most dangerous attacks in Europe.
Harry Kane and Son Heung-min set a new Premier League goal combinations record of 14 last weekend against Crystal Palace, while Gareth Bale has netted two goals in each of his last two top-flight games.
"It's very difficult because the level of quality, precision, understanding and chemistry that they have between them makes them probably one of the most special ones in Europe," Arteta said ahead of Sunday's derby.
"They don't need much. They are able to create their own chances, they are able to link as a team.
"So it is really difficult to do that, but we will prepare the game well to try to stop them obviously."
