Ben Davies admits Tottenham have no margin for error in their pursuit of Manchester City.
Spurs travel to Arsenal in a north London derby that Davies says his team must win to stand a chance of catching Pep Guardiola's side.
Tottenham are eight points behind City, who face Leicester, with a far inferior goal difference but Davies is still eyeing a tilt at the title.

'My focus is on Arsenal, of course there is no margin for error,' said Davies.
