You're right. We are still in the driving seat.
We've got seven homes games left compared to Arsenal and Spurs with six and Man City with five.
From the seven away fixtures against those we've got to play at home, we won six and drew one.
From the five home fixtures against those we've got to play away, we won four and drew one.
If we could replicate those results, we've won the league irrespective of what the others do. As Arsenal and Spurs play each other, one of them would need to win that game and take a total of 34/36 points to overtake us. They're not going to do that as both sides have several tough fixtures left (aside from playing each other). Arsenal have away games at Everton, Man City, Man Utd and West Ham. Spurs have got to go to Chelsea, Liverpool and West Ham.
I think 77 points will be enough to win the league this year. Eight wins, two draws and two defeats.
Of course, it's easier said than done, but we're now over the fixtures we've found toughest. From here on in, it's up to us to outplay most of the opposition we've already proved superior to. If we do, Harry Kane, Alexis Sanchez and co can all go score and dive about til the cows come home and will not matter at all.
