Looking forward just gets your head scrambled. Just 2 - 3 weeks ago, before the north London derby, I was praying for Arsenal to beat Spurs because at that time top 4 looked out of the question and we needed to focus on topping Spurs. Now, I'm thinking what a pity Spurs didn't get something out of that game.
The moral there is don't worry about what others are doing. If you do well enough, they are irrelevant. Push on, blues!
