The leading lights in the Premier League can be identified by their goal difference, according to Arsène Wenger.
Just two points separate the current top three of Manchester United, Arsenal and Chelsea before a 10-point gap to Tottenham and Manchester City.
But there is a chasm between the goal difference of the front-runners and that of the chasing pack. The top three are all sitting pretty on plus 34 while Spurs have plus 18. It suggests that not only do United, Arsenal and Chelsea win often - they also win emphatically.
And they will need to keep doing so, because Wenger thinks goal difference could decide the destination of the Premier League trophy come May.
"It could be that tight," said Wenger.
"Let's go well through the next four games and then we will see what the situation is. It looks very tight.
"The goal difference is an indication of the quality of the teams.
"You could see that is 34 for the top three and after that it goes down to 18 so there is an indication there."
