Boro would be a good shout. Did a decent job at Leeds. Having seen various comments from Swansea supporters I'm not sure that the accepted wisdom that Swansea were mad to sack him is quite right, but Boro could probably do worse.
Leeds capitulated at the end of the season after they beat us, although why that is remains a mystery. Their managers seem to come and go, regardless of whether they're doing well or badly.
