I want to say the Premier League winner cannot be fully confirm after see the competitive situation in the standings.
There is more than 10 match that have not been play by each team in the Premier League.
It's true that Arsenal currently leads the EPL standings with a collection of 69 points, followed by Manchester City with a collection of 61 points, currently the two teams is 8 points adrift. But Manchester City still has 1 match left because they have only play 27 match while Arsenal have play 28 match. If Man City can win the remaining match, then their points will be 64 or only 5 points away from Arsenal.
It is still very possible to change positions one and two
