With the present stats, Liverpool is pulling alright, they are giving this season their best. But Man City has won four consecutive seasons now, and I'm not sure they would want someone else to take the cup from them, nobody likes to be dethroned.
Also, Man City still have the potentials, and with what have been played, and the bar they've raised, I don't think any team is ready or prepared to challenge them because they'll also be training relentlessly.
They also have the top goal scorer (Halland with 7 goals in 3 games) in top 5 leagues in Europe. Halland is still young and active, ready to burn it all out to retain the trophy. So think about it , man city might win it again for the 5th season straight.
