Whilst admittedly that is a gap and would be difficult to close, beat them 2-0 twice and that 14 goal difference becomes 6. Assuming they are losing another game in the remaining 10, that puts it at 5, assuming we match them goal for goal in other games. having a swing of 14 goals in 10 games is far from impossible, assuming we beat them twice (which we would need to do anyway to give ourselves a chance).
Murty needs to hammer home to the team the importance of the goal difference. It might be the difference between us finishing 2nd or 3rd, but it also might be the difference in winning title or not, so we need to get some good positive results. A couple 4 and 5 nils would be very helpful.
