I repeat, when has Steptonho taken over a team that was underperforming? Look at where the various teams he managed finished before he showed up
Porto
2001-2: Finished third
Chelsea
2003-4: Finished second
Inter
2007-8: Won the league
Los Ladrones
2008-9: Finished second
Chelsea
2012-13: Finished third, won Europa League
Manchester United
2015-16: Finished fifth, won FA Cup
So at best you can say he's taken over one team that was struggling, and did he turn them around? Did he buggery - they're currently two points above the relegation zone and having a far worse season than us, but for some reason all the ex-Man Utd and ex-Arsenal pundits are not mentioning that little detail...
With regards to Utd, I thought he was taking the piss when he said coming second with them was his greatest achievement but looking at how **** they are under Ole, he may have been telling the truth!
