Brentford still have Man Utd, Man City and Liverpool to play.
Chelsea still have Man Utd and Liverpool
Liverpool still have Brentford, Chelsea, Us and Everton and Man Utd
Man Utd still have Chelsea, Brentford and Liverpool
Everyone is playing each other so everyone has to drop points. We only need to finish above 2 of those. 7 points will do it I reckon. Liverpool would need 10pts to overtake us which would mean taking points off everyone around us. Chelsea would need 14pts which would mean them having to beat Liverpool and Man Utd making Liverpool's 10pts less likely. Brentford would need 15 pts meaning they'd have to beat Liverpool, again making Liverpool's 10pts less likely.
Bottom line, it's firmly in our own hands now and we're in a much better position than before the West Ham game.
