There will come a point next summer, if Swansea somehow pull off the escape, that the usual bonuses for survival will be shared among the squad. If the others had any self-awareness they'd see to it that Gylfi Sigurdsson walks away with the majority of the loot.
That is not to say Swansea will stay up. Their deficiencies are such that they are still more likely to go down. But they are off the bottom, out of the relegation zone and have a fighting chance, most of which is down to the one legitimately excellent player in their squad.
