Mauricio Pochettino was widely praised for his one and a half seasons at Southampton. His success got him the Tottenham job.
But, upon reflection, as so often happens in the fast-changing world of football, things now look a little different. Both for the Argentine himself and Southampton.
That, quite simply, is because Southampton already have as many points as they did last season - in six games less under new boss Ronald Koeman. Spurs, meanwhile, are suffering a similar fate to Pochettino's Saints side: they are running out of steam, finishing their year with a whimper.
Has Koeman's success at Southampton, then, overshadowed that of his predecessor and potentially exposed the Argentine's flaws?
With a nine-point advantage over Swansea, there is realistically little chance Koeman's men can finish lower than seventh this campaign, with a fifth-placed finish still very much on the cards.
Pochettino, though, has been criticised by Tottenham fans for a worrying lack of tactical nous, an over-emphasis on fitness and a lack of adaptability. It can also be argued the Spurs boss had a better squad at his disposal during his time at Southampton...
So has Koeman outshone Pochettino and exposed his flaws with his St Mary's success?
